+### Description
+
+This patch implements sequences for chained keybindings (like the dwm [keychord](https://dwm.suckless.org/patches/keychord/) patch).
+
+_Notes_: 
+- The maximum number of sequences is set to `5` in the `Keychord` struct for a given keybinding
+- This bundles the [keycodes](https://github.com/djpohly/dwl/wiki/keycodes) patch as an implementation dependency, maybe that can be avoided...
+
+### Example
+
+In the example below, the menu command is bound to the sequence `Control-t Control-O`.
+
+```C
+static const Keychord keychords[] = {
+  /* Note that Shift changes certain key codes: c -> C, 2 -> at, etc. */
+  /* count key_sequences                          function  argument */
+  { 2, {{MODKEY, PREFIXKEY}, {MOD_CONTROL, Key_o}},  spawn,    { .v = menucmd } }
+};
+```
