-# Use keyboard shortcuts to select and copy text.
-
-# Usage: put the following lines in your .Xdefaults/.Xresources:
-#   URxvt.perl-ext-common: ...,keyboard-select
-#   URxvt.keysym.M-Escape: perl:keyboard-select:activate
-# The following line overwrites the default Meta-s binding and allows to
-# activate keyboard-select directly in backward search mode:
-#   URxvt.keysym.M-s: perl:keyboard-select:search
-
-# Use Meta-Escape to activate selection mode, then use the following keys:
-#   h/j/k/l:    Move cursor left/down/up/right (also with arrow keys)
-#   g/G/0/^/$/H/M/L/f/F/;/,/w/W/b/B/e/E: More vi-like cursor movement keys
-#   '/'/?:      Start forward/backward search
-#   n/N:        Repeat last search, N: in reverse direction
-#   Ctrl-f/b:   Scroll down/up one screen
-#   Ctrl-d/u:   Scroll down/up half a screen
-#   v/V/Ctrl-v: Toggle normal/linewise/blockwise selection
-#   y/Return:   Copy selection to primary buffer, Return: deactivate afterwards
-#   q/Escape:   Deactivate keyboard selection mode
