Movement Keys
-------------
`h', `j', `k', `l' move the cursor line by line or column by column.
`0', `^' and `$' move to the leftmost column or to the first or last
non-whitespace character on the line.
`H', `M' and `L' move the cursor to the leftmost column of the top,
center or bottom line of the window.
`+' and `-' move the cursor to the leftmost column of the next or
previous line.
`G' moves to the specified absolute line (default: end of buffer).
`|' moves to the specified absolute column.
`w', `b', `e' move the cursor word by word.
`C-u' and `C-d' scroll the display up/down by the specified amount of
lines while preserving the cursor position. (Default: half screenfull).
`C-b' and `C-f' move the cursor up/down a full screen.
`g' moves to the beginning of the buffer.
`%' jumps to the specified percentage of the buffer.
Note that Emacs-style movement keys can be specified by a .screenrc
command. (`markkeys "h=^B:l=^F:$=^E"') There is no simple method for a
full emacs-style keymap, however, as this involves multi-character
codes.
