Commands and Shortcuts

Most tasks in Lite XL are performed with commands, based on a simple system of predicates and user-defined actions. Commands can be bound to keyboard shortcuts, which will be run when the corresponding keys or mouse buttons are pressed.

A common idiom used in Lite XL is to listen to View:on_mouse_moved() and record the item that the cursor is hovering on; and then add a command to set the hovered item as the selected item when the left-clicks the item. This idiom does not require the user to listen to View:on_mouse_click() and allows unifying the mouse and keyboard handling code.
