+keyboard_select
+===============
+
+Description
+-----------
+
+This patch allows you to select and copy text to primary buffer with keyboard
+shortcuts like the perl extension “keyboard-select” for urxvt.
+
+Instructions
+------------
+The patch changes the “config.def.h”. Delete your
+“config.h” or add the shortcut below if you use a custom one.
+
+ Shortcut shortcuts[] = {
+ ...
+ { TERMMOD, XK_Escape, keyboard_select, { 0 } },
+ };
+
+
+Notes
+-----
+
+When you run "keyboard_select", you have 3 modes available :
+
+* move mode : to set the start of the selection;
+* select mode : to activate and set the end of the selection;
+* input mode : to enter the search criteria.
+
+<br>
+
+Shortcuts for move and select modes :
+
+ h, j, k, l: move cursor left/down/up/right (also with arrow keys)
+ !, _, *: move cursor to the middle of the line/column/screen
+ Backspace, $: move cursor to the beginning/end of the line
+ PgUp, PgDown : move cursor to the beginning/end of the column
+ Home, End: move cursor to the top/bottom left corner of the screen
+ /, ?: activate input mode and search up/down
+ n, N: repeat last search, up/down
+ s: toggle move/selection mode
+ t: toggle regular/rectangular selection type
+ Return: quit keyboard_select, keeping the highlight of the selection
+ Escape: quit keyboard_select
+
+With h,j,k,l (also with arrow keys), you can use a quantifier. Enter a number before hitting the appropriate key.
+
+<br>
+
+Shortcuts for input mode :
+
+ Return: Return to the previous mode
