 Pressing B<Shift-Insert> causes the value of the PRIMARY selection to be
 inserted too.
+rxvt-unicode also provides the bindings B<Ctrl-Meta-c> and
+<Ctrl-Meta-v> to interact with the CLIPBOARD selection. The first
+binding causes the value of the internal selection to be copied to the
+CLIPBOARD selection, while the second binding causes the value of the
+CLIPBOARD selection to be inserted.

 =head1 CHANGING FONTS
 Changing fonts (or font sizes, respectively) via the keypad is not yet
 and character codes using the keyboard. It consists of 4 parts. The
 first part is available if rxvt-unicode has been compiled with
 C<--enable-frills>, the rest is available when rxvt-unicode was compiled
 with C<--enable-iso14755>.

 =item * 5.1: Basic method
 This allows you to enter unicode characters using their hexcode.
 In addition to the default foreground and background colours,
 B<@@RXVT_NAME@@> can display up to 88/256 colours: 8 ANSI colours plus
 high-intensity (potentially bold/blink) versions of the same, and 72 (or
 240 in 256 colour mode) colours arranged in an 4x4x4 (or 6x6x6) colour RGB
 cube plus a 8 (24) colour greyscale ramp.
+B<@@RXVT_NAME@@> supports direct 24-bit fg/bg RGB colour escapes
+C< ESC [ 38 ; 2 ; R ; G ; Bm > / C< ESC [ 48 ; 2; R ; G ; Bm >. However the
+number of 24-bit colours that can be used is limited: an internal 7x7x5 (256
+colour mode) or 6x6x4 (88 colour mode) colour cube is used to index into the
+24-bit colour space. When indexing collisions happen, the nearest old colour in
+the cube will be adapted to the new 24-bit RGB colour. That means one cannot
+use many similar 24-bit colours. It's typically not a problem in common
+scenarios.
 Here is a list of the ANSI colours with their names.
 =begin table
 The following text gives values for the standard 88 colour mode (and
 values for the 256 colour mode in parentheses).
 The RGB cube uses indices 16..79 (16..231) using the following formulas:
-   index_88  = (r *  4 + g) *  4 + b + 16   # r, g, b = 0..3
+   index_88  = (r * 4 + g) * 4 + b + 16   # r, g, b = 0..3
-   index_256 = (r * 16 + g) * 16 + b + 16   # r, g, b = 0..15
+   index_256 = (r * 6 + g) * 6 + b + 16   # r, g, b = 0..5
 The grayscale ramp uses indices 80..87 (232..239), from 10% to 90% in 10%
 steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
 the RGB cube.
