+Description
+-----------
+
+This patch allows you to work with 16 color palettes and change them on the
+fly.
+
+
+Instructions
+------------
+The patch changes the “config.def.h”.
+Delete your “config.h” or change it manually if you use a custom one.
+
+
+Notes
+-----
+It uses the following shortcuts :
+
+ Shortcut shortcuts[] = {
+ ...
+ { TERMMOD, XK_F1, setpalette, {.i = 0} },
+ { TERMMOD, XK_F2, setpalette, {.i = 1} },
+ { TERMMOD, XK_F3, setpalette, {.i = 2} },
+ { TERMMOD, XK_F4, setpalette, {.i = 3} },
+ { TERMMOD, XK_F5, setpalette, {.i = 4} },
+ { TERMMOD, XK_F6, setpalette, {.i = 5} },
+ { TERMMOD, XK_F7, setpalette, {.i = 6} },
+ { TERMMOD, XK_F8, setpalette, {.i = 7} },
+ { TERMMOD, XK_F9, setpalette, {.i = 8} },
