How would I mod_rewrite "/~a1Pha" and "/=a1Pha" to "/paste/a1Pha.htm"? (internally & externally)

Basically I want to shorten URLs on my html pasting site (, by using "/~a1Pha" instead of "/paste/a1Pha". The ID is 5 numbers and letters, both cases.

For example:
/~idnum serves /paste/idnum.htm
/=idnum serves /paste/idnum.htm
/paste/idnum redirects to /~idnum (to update any old urls to new ones)

I have mod_rewrite enabled and working.

Edit: Figured it out:
RewriteRule ^~?([a-zA-Z0-9]+)$ paste/$1.htm [L]
RewriteRule ^=?([a-zA-Z0-9]+)$ paste/$1.htm [L]

paste(1)						      General Commands Manual							  paste(1)

       paste - merge file data

       paste file1 file2...
       paste -dlist file1 file2...
       paste -s [-dlist] file1 file2...

       In  the	first  two forms, concatenates corresponding lines of the given input files file1, file2, etc.	It treats each file as a column or
       columns of a table and pastes them together horizontally (parallel merging).

       In the last form, the command combines subsequent lines of the input file (serial merging).

       In all cases, lines are glued together with the tab character, or with characters from an optionally specified  list.   Output  is  to  the
       standard output, so it can be used as the start of a pipe, or as a filter, if - is used in place of a file name.

       -       Used in place of any file name, to read a line from the standard input.	(There is no prompting).

       -dlist  Replaces  characters  of  all but last file with nontabs characters (default tab).  One or more characters immediately following -d
	       replace the default tab as the line concatenation character.  The list is used circularly, i. e. when exhausted, it is reused.	In
	       parallel  merging  (i. e. no -s option), the lines from the last file are always terminated with a new-line character, not from the
	       list.  The list may contain the special escape sequences: 
 (new-line), 	 (tab), \ (backslash), and  (empty string, not a null
	       character).   Quoting  may  be  necessary,  if characters have special meaning to the shell (for example, to get one backslash, use
	       -d"\\" ).
	       Without this option, the new-line characters of each but the last file (or last line in case of the -s option) are  replaced  by  a
	       tab character.  This option allows replacing the tab character by one or more alternate characters (see below).

       -s      Merges  subsequent  lines  rather  than	one  from  each input file.  Use tab for concatenation, unless a list is specified with -d
	       option.	Regardless of the list, the very last character of the file is forced to be a new-line.

       ls | paste -d" " -
       list directory in one column
       ls | paste - - - -
       list directory in four columns
       paste -s -d"	
" file
       combine pairs of lines into lines

       line too long
		 Output lines are restricted to 511 characters.

       too many files
		 Except for -s option, no more than 12 input files may be specified.
