Modifying Key Bindings

You can change key bindings by editing the keyBindings configuration section.

Here is how you can configure the Right arrow key to open the selected directory and Left to go up:

keyBindings {
    "Left" { id "core.go.up" }
    "Right" { id "core.open.directory" }
}

core.go.up and core.open.directory are action identifiers. You can find them right in the Action panel: hold the Opt key, and the identifiers will be shown.

To unset a default key binding, pass null as a value:

keyBindings {
    "F5" null
}

Shortcuts Without Modifier Keys

You can set up keybindings for letter keys, e.g.:

keyBindings {
    "H" "core.move.left"
    "L" "core.move.right"
    "K" "core.move.up"
    "J" "core.move.down"
}

However, you might realize the added bindings don’t work, and Quick Select is activated instead. You can change the behavior so Quick Select activates only by pressing the / key:

behavior {
	quickSelect {
        activateOnAnyCharacter true
    }
}

Now Marta recognizes your key bindings and moves the cursor accordingly.

Action Arguments

Some Marta actions allow you to specify its arguments right in the configuration file.

Here is how you can bind Alt+H to open the home folder:

keyBindings {
    "Alt+H" {
        id "core.open.directory"
        src "~"
    }
}
