 some hooks will not consider underlying scopes depending on what context
 they are bound to be run into, e.g. the `BufWritePost` hook is a buffer
 hook, and will not consider the `window` scope.
+
+While defining hook commands with a `%sh{}` block, you have access to
+the following expansions:
+
+* `kak_hook_param`: filtering text passed to the currently executing hook
+* `kak_hook_param_capture_N`: text captured by the hook filter regex capture N
+
+Disabling Hooks
+---------------
+
+Any normal mode command can be prefixed with `\` which will disable hook
+execution for the duration for the command (including the duration of modes
+the command could move to, so `\i` will disable hooks for the whole insert
+session).
+
+As autoindentation is implemented in terms of hooks, this can be used to
+disable it when pasting text.
+
+A less temporary alternative is to set the `disabled_hooks` option which
+accepts a regex describing which hooks won't be executed.
+For example indentation hooks can be disabled with '.*-indent'.
+
+Finally, hook execution can be disabled while using the `exec` or `eval`
+commands by using the `-no-hooks` switch.
