Does ^K appear to be a single character on the screen (that is, when you move the cursor over it (in vi), does the cursor move only to the ^ or also to the K)?

catting the file will typically not show hidden characters. Use the -v option to see hidden characters.

NAME
keynav - a keyboard-driven mouse cursor mover SYNOPSIS
keynav DESCRIPTION
Keynav makes your keyboard a fast mouse cursor mover. You can move the cursor to any point on the screen with a few key strokes. It also simulates mouse click. You can do everything mouse can do with a keyboard. HOW TO USE
Run keynav, and activate it by pressing Ctrl+; (semicolon). You should see a thin frame on the screen with a cross in it. Default configuration: * h : select the left half of the region * j : select the bottom half of the region * k : select the top half of the region * l : select the right half of the region * Shift+h : move the region left * Shift+j : move the region down * Shift+k : move the region up * Shift+l : move the region right * Semicolon: move the cursor to the center of the selected region * Spacebar : move the cursor and left-click * Escape : cancel the move CONFIGURATION
You can configure your own key setting. There is an example in /usr/share/doc/keynav/keynavrc. Copy it to $HOME/.keynavrc and edit it as you like. CONFFILE COMMANDS
* start : activate keynav * end : deactivate keynav * cut-left : select the left half of the region * cut-right : select the right half of the region * cut-up : select the top half of the region * cut-down : select the bottom half of the region * move-left : move the region left * move-right : move the region right * move-up : move the region up * move-down : move the region down * warp : move the cursor to the center of the selected region * click 1 : left-click * click 2 : middle-click * click 3 : right-click * doubleclick 1: left-click twice quickly * doubleclick 2: middle-click twice quickly * doubleclick 3: right-click twice quickly * drag <button> [keyseq]: toggle dragging mode for the given button Example: "drag 1 alt" to do a alt+click-drag * grid <rows>x<columns> : change the grid layout of the selection Example: "grid 2x3" to cut screen to 6 cells * cell-select <row>x<column>: select a specific cell in the grid * cell-select <cell> : select a specific cell in the grid AUTHOR
