+the available gestures and actions.
+
+#### UinputAction
+
+Send keyboard events when a gesture is executed. First, it presses all the
+modifier keys in the order they appear. Then, it clicks (presses and depresses)
+all the sequence keys one after another. After that, all modifier keys get
+depressed in the reverse order.
+
+    // Example: start omni-completion in vim
+    UinputAction (
+
+        // These keys are pressed for all the duration of the action
+        modifiers: ["RightControl"],
+
+        // There keys are pressed one at a time
+        sequence: ["X", "O"],
+
+    )
+
+#### ShellCommandAction
+
+Run a command in the `sh` shell. All wildcards and special symbols get
+interpreted like the shell always does.
+
+    // Example: toggle a scroll lock LED (works in X11 only)
+    CommandAction (
+        command: r#"
+            on=$(xset -q | grep 'Scroll Lock:' | cut -d ":" -f 7)
+            echo $on
+            if [ $on == "off" ]; then
+               xset led named "Scroll Lock"
+            else
+               xset -led named "Scroll Lock"
+            fi
+        "#,
+    ),
+
+The example above features a raw string literal. It's delimited by `r###"` and
+`"###` with any number of `#` symbols, and any symbol can appear inside this
+string. You can use raw string literals anywhere a string is expected in
+config, but it's most useful with this and the next action.
+
+#### CommandAction
+
+Like `ShellCommandAction`, but skip the shell and invoke the command literally.
+The difference between this and that is like a difference between `system` and
+`execv`.
+
+    // Example: unclutter desktop in KDE
+    CommandAction (
+        // Path can be absolute (/usr/bin/qdbus-qt5) or just a command name. In
+        // the second case it's looked up in $PATH
+        path: "qdbus-qt5",
+        args: [
+            "org.kde.KWin",
+            "/KWin",
+            "unclutterDesktop",
+        ],
+        // Actually this example doesn't work because of
+        // https://bugs.freedesktop.org/show_bug.cgi?id=52202
+    ),
+
+Note that you can use this instead of the previous action. In fact, this is
+what you should do if you want your command to run in bash or zsh instead of
+sh.
+
+    CommandAction (
+        path: "/usr/bin/env",
+        args: [
+            "bash",
+            "-c",
+            r##" your command goes here "##,
+        ],
+    ),
