 This is a plugin that makes [`tmux`][6] behave more like a typical
 [dynamic window manager][7]. It is heavily inspired by [`i3wm`][8], and 
 most keybindings are taken [directly from there][1]. However, I have made

 The <kbd>Alt</kbd> + <kbd>0</kbd> and <kbd>Alt</kbd> + <kbd>Shift</kbd> + <kbd>0</kbd> 
 bindings are "smart": depending on `base-index`, they either act on workspace 0 or 10.
 
+The following options can be used to override some keys mentioned in the above table (if they're not

+- `set -g @tilish-split_vsplit "..."` (default <kbd>s</kbd>)
+- `set -g @tilish-split_only "..."` (default <kbd>S</kbd>)
+- `set -g @tilish-vsplit_split "..."` (default <kbd>v</kbd>)
+- `set -g @tilish-vsplit_only "..."` (default <kbd>V</kbd>)
+- `set -g @tilish-tiled "..."` (default <kbd>t</kbd>)

+- `set -g @tilish-refresh "..."` (default <kbd>r</kbd>)
+- `set -g @tilish-rename "..."` (default <kbd>n</kbd>)

 The keybindings that move panes between workspaces assume a US keyboard layout.
 However, you can configure `tilish` for international keyboards by providing a string
 `@tilish-shiftnum` prepared by pressing <kbd>Shift</kbd> +
