Previous command

Hi,

i would like to retrieve (only retrieve, not execute) a previous command which i executed on the command prompt. I tried the 'up arrow' key, but its not working. Instead,it showed me some funny characters. I searched around and i found the way to do it was using the way below. Several websites quoted as saying ".. using control key ^P .. ". What keys do i type to get the control P ? I tried shift + P and Ctrl + P, neither worked.

NAME
keytables - keyboard table descriptions for loadkeys and dumpkeys DESCRIPTION
These files are used by loadkeys(1) to modify the translation tables used by the keyboard streams module and generated from those transla- tion tables. See loadkeys(1). Any line in the file beginning with # is a comment, and is ignored. # is treated specially only at the beginning of a line. Other lines specify the values to load into the tables for a particular keystation. The format is either: key number list_of_entries or swap number1 with number2 or key number1 same as number2 or a blank line, which is ignored. key number list_of_entries sets the entries for keystation number from the list given. An entry in that list is of the form tablename code where tablename is the name of a particular translation table, or all. The translation tables are: base entry when no shifts are active shift entry when "Shift" key is down caps entry when "Caps Lock" is in effect ctrl entry when "Control" is down altg entry when "Alt Graph" is down numl entry when "Num Lock" is in effect up entry when a key goes up All tables other than up refer to the action generated when a key goes down. Entries in the up table are used only for shift keys, since the shift in question goes away when the key goes up, except for keys such as "Caps Lock" or "Num Lock"; the keyboard streams module makes the key look as if it were a latching key. A table name of all indicates that the entry for all tables should be set to the specified value, with the following exception: for entries with a value other than hole, the entry for the numl table should be set to nonl, and the entry for the up table should be set to nop. The code specifies the effect of the key in question when the specified shift key is down. A code consists of either: o A character, which indicates that the key should generate the given character. The character can either be a single character, a sin- gle character preceded by ^ which refers to a "control character" (for instance, ^c is control-C), or a C-style character constant enclosed in single quote characters ('), which can be expressed with C-style escape sequences such as for RETURN or 00 for the null character. Note that the single character may be any character in an 8-bit character set, such as ISO 8859/1. o A string, consisting of a list of characters enclosed in double quote characters ("). Note that the use of the double quote character means that a code of double quote must be enclosed in single quotes. o One of the following expressions: shiftkeys+leftshift the key is to be the left-hand "Shift" key shiftkeys+rightshift the key is to be the right-hand "Shift" key shiftkeys+leftctrl the key is to be the left-hand "Control" key shiftkeys+rightctrl the key is to be the right-hand "Control" key shiftkeys+alt the key is to be the "Alt" shift key shiftkeys+altgraph the key is to be the "Alt Graph" shift key shiftkeys+capslock the key is to be the "Caps Lock" key shiftkeys+shiftlock the key is to be the "Shift Lock" key shiftkeys+numlock the key is to be the "Num Lock" key buckybits+systembit the key is to be the "Stop" key in SunView; this is normally the L1 key, or the SETUP key on the VT100 key- board buckybits+metabit the key is to be the "meta" key. That is, the "Left" or "Right" key on a Sun-2 or Sun-3 keyboard or the "dia- mond" key on a Sun-4 keyboard compose the key is to be the "Compose" key ctrlq on the "VT100" keyboard, the key is to transmit the control-Q character (this would be the entry for the "Q" key in the ctrl table) ctrls on the "VT100" keyboard, the key is to transmit the control-S character (this would be the entry for the "S" key in the ctrl table) noscroll on the "VT100" keyboard, the key is to be the "No Scroll" key string+uparrow the key is to be the "up arrow" key string+downarrow the key is to be the "down arrow" key string+leftarrow the key is to be the "left arrow" key string+rightarrow the key is to be the "right arrow" key string+homearrow the key is to be the "home" key fa_acute the key is to be the acute accent "floating accent" key fa_cedilla the key is to be the cedilla "floating accent" key fa_cflex the key is to be the circumflex "floating accent" key fa_grave the key is to be the grave accent "floating accent" key fa_tilde the key is to be the tilde "floating accent" key fa_umlaut the key is to be the umlaut "floating accent" key nonl this is used only in the Num Lock table; the key is not to be affected by the state of Num Lock pad0 the key is to be the "0" key on the numeric keypad pad1 the key is to be the "1" key on the numeric keypad pad2 the key is to be the "2" key on the numeric keypad pad3 the key is to be the "3" key on the numeric keypad pad4 the key is to be the "4" key on the numeric keypad pad5 the key is to be the "5" key on the numeric keypad pad6 the key is to be the "6" key on the numeric keypad pad7 the key is to be the "7" key on the numeric keypad pad8 the key is to be the "8" key on the numeric keypad pad9 the key is to be the "9" key on the numeric keypad paddot the key is to be the "." key on the numeric keypad padenter the key is to be the "Enter" key on the numeric keypad padplus the key is to be the "+" key on the numeric keypad padminus the key is to be the "-" key on the numeric keypad padstar the key is to be the "*" key on the numeric keypad padslash the key is to be the "/" key on the numeric keypad padequal the key is to be the "=" key on the numeric keypad padsep the key is to be the "," (separator) key on the numeric keypad lf(n) the key is to be the left-hand function key n rf(n) the key is to be the right-hand function key n tf(n) the key is to be the top function key n bf(n) the key is to be the "bottom" function key n nop the key is to do nothing error this code indicates an internal error; to be used only for keystation 126, and must be used there idle this code indicates that the keyboard is idle (that is, has no keys down); to be used only for all entries other than the numl and up table entries for keystation 127, and must be used there oops this key exists, but its action is not defined; it has the same effect as nop reset this code indicates that the keyboard has just been reset; to be used only for the up table entry for keysta- tion 127, and must be used there. swap number1 with numberexchanges the entries for keystations number1 and number2. key number1 same as numbsets the entries for keystation number1 to be the same as those for keystation number2. If the file does not specify entries for keystation number2, the entries currently in the translation table are used; if the file does specify entries for keystation number2, those entries are used. EXAMPLES
Example 1: Example of setting multiple keystations. The following entry sets keystation 15 to be a "hole" (that is, an entry indicating that there is no keystation 15); sets keystation 30 to do nothing when Alt Graph is down, generate "!" when Shift is down, and generate "1" under all other circumstances; and sets keystation 76 to be the left-hand Control key. key 15 all hole key 30 base 1 shift ! caps 1 ctrl 1 altg nop key 76 all shiftkeys+leftctrl up shiftkeys+leftctrl Example 2: Exchange DELETE and BACKSPACE keys The following entry exchanges the Delete and Back Space keys on the Type 4 keyboard: swap 43 with 66 Keystation 43 is normally the Back Space key, and keystation 66 is normally the Delete key. Example 3: Disable CAPS LOCK key The following entry disables the Caps Lock key on the Type 3 and U.S. Type 4 keyboards: key 119 all nop Example 4: Standard translation tables for the U.S. Type 4 keyboard The following specifies the standard translation tables for the U.S. Type 4 keyboard: key 0 all hole key 1 all buckybits+systembit up buckybits+systembit key 2 all hole key 3 all lf(2) key 4 all hole key 5 all tf(1) key 6 all tf(2) key 7 all tf(10) key 8 all tf(3) key 9 all tf(11) key 10 all tf(4) key 11 all tf(12) key 12 all tf(5) key 13 all shiftkeys+altgraph up shiftkeys+altgraph key 14 all tf(6) key 15 all hole key 16 all tf(7) key 17 all tf(8) key 18 all tf(9) key 19 all shiftkeys+alt up shiftkeys+alt key 20 all hole key 21 all rf(1) key 22 all rf(2) key 23 all rf(3) key 24 all hole key 25 all lf(3) key 26 all lf(4) key 27 all hole key 28 all hole key 29 all ^[ key 30 base 1 shift ! caps 1 ctrl 1 altg nop key 31 base 2 shift @ caps 2 ctrl ^@ altg nop key 32 base 3 shift # caps 3 ctrl 3 altg nop key 33 base 4 shift $ caps 4 ctrl 4 altg nop key 34 base 5 shift % caps 5 ctrl 5 altg nop key 35 base 6 shift ^ caps 6 ctrl ^^ altg nop key 36 base 7 shift & caps 7 ctrl 7 altg nop key 37 base 8 shift * caps 8 ctrl 8 altg nop key 38 base 9 shift ( caps 9 ctrl 9 altg nop key 39 base 0 shift ) caps 0 ctrl 0 altg nop key 40 base - shift _ caps - ctrl ^_ altg nop key 41 base = shift + caps = ctrl = altg nop key 42 base ` shift ~ caps ` ctrl ^^ altg nop key 43 all '' key 44 all hole key 45 all rf(4) numl padequal key 46 all rf(5) numl padslash key 47 all rf(6) numl padstar key 48 all bf(13) key 49 all lf(5) key 50 all bf(10) numl padequal key 51 all lf(6) key 52 all hole key 53 all ' ' key 54 base q shift Q caps Q ctrl ^Q altg nop key 55 base w shift W caps W ctrl ^W altg nop key 56 base e shift E caps E ctrl ^E altg nop key 57 base r shift R caps R ctrl ^R altg nop key 58 base t shift T caps T ctrl ^T altg nop key 59 base y shift Y caps Y ctrl ^Y altg nop key 60 base u shift U caps U ctrl ^U altg nop key 61 base i shift I caps I ctrl ' ' altg nop key 62 base o shift O caps O ctrl ^O altg nop key 63 base p shift P caps P ctrl ^P altg nop key 64 base [ shift { caps [ ctrl ^[ altg nop key 65 base ] shift } caps ] ctrl ^] altg nop key 66 all '177' key 67 all compose key 68 all rf(7) numl pad7 key 69 all rf(8) numl pad8 key 70 all rf(9) numl pad9 key 71 all bf(15) numl padminus key 72 all lf(7) key 73 all lf(8) key 74 all hole key 75 all hole key 76 all shiftkeys+leftctrl up shiftkeys+leftctrl key 77 base a shift A caps A ctrl ^A altg nop key 78 base s shift S caps S ctrl ^S altg nop key 79 base d shift D caps D ctrl ^D altg nop key 80 base f shift F caps F ctrl ^F altg nop key 81 base g shift G caps G ctrl ^G altg nop key 82 base h shift H caps H ctrl '' altg nop key 83 base j shift J caps J ctrl ' ' altg nop key 84 base k shift K caps K ctrl 'v' altg nop key 85 base l shift L caps L ctrl ^L altg nop key 86 base ; shift : caps ; ctrl ; altg nop key 87 base ''' shift '"' caps ''' ctrl ''' altg nop key 88 base '\' shift | caps '\' ctrl ^ altg nop key 89 all ' ' key 90 all bf(11) numl padenter key 91 all rf(10) numl pad4 key 92 all rf(11) numl pad5 key 93 all rf(12) numl pad6 key 94 all bf(8) numl pad0 key 95 all lf(9) key 96 all hole key 97 all lf(10) key 98 all shiftkeys+numlock key 99 all shiftkeys+leftshift up shiftkeys+leftshift key 100 base z shift Z caps Z ctrl ^Z altg nop key 101 base x shift X caps X ctrl ^X altg nop key 102 base c shift C caps C ctrl ^C altg nop key 103 base v shift V caps V ctrl ^V altg nop key 104 base b shift B caps B ctrl ^B altg nop key 105 base n shift N caps N ctrl ^N altg nop key 106 base m shift M caps M ctrl ' ' altg nop key 107 base , shift < caps , ctrl , altg nop key 108 base . shift > caps . ctrl . altg nop key 109 base / shift ? caps / ctrl ^_ altg nop key 110 all shiftkeys+rightshift up shiftkeys+rightshift key 111 all ' ' key 112 all rf(13) numl pad1 key 113 all rf(14) numl pad2 key 114 all rf(15) numl pad3 key 115 all hole key 116 all hole key 117 all hole key 118 all lf(16) key 119 all shiftkeys+capslock key 120 all buckybits+metabit up buckybits+metabit key 121 base ' ' shift ' ' caps ' ' ctrl ^@ altg ' ' key 122 all buckybits+metabit up buckybits+metabit key 123 all hole key 124 all hole key 125 all bf(14) numl padplus key 126 all error numl error up hole key 127 all idle numl idle up reset SEE ALSO
