Key mappings

All shortcuts can be edited in the Tools > Options > Editor > Key Mappings and the preset schemes can be loaded using the Choose Key Mapping Scheme dialog.

For what does each shortcut does, see the Lazarus tutorial.


The default key mapping for Windows fits quite well under Gnome.


The default key mapping for Windows fits quite well under KDE. Some keys like F9 are used by KDE.

macOS, Apple style

macOS has quite different key policies. For example most F keys are used by the OS, there are no menu Alt shortcuts and there are substantial guidelines (contrary to Linux and Windows where only a few keys are standardised to work the same under all programs).

The Apple Human Interface Guidelines - keyboard section deals with key bindings for macOS.

Xcode is Apple's own integrated development environment. Here are the Xcode shortcuts: Xcode Shortcuts B W.png

macOS, Lazarus style

A macOS key map is available for Lazarus and can be set via Tools > Options > Editor > Key Mappings / Load a scheme which opens the Choose Key Mapping Scheme dialog. This preset scheme is based on the "macOS, Apple style" with some keys overridden (see below).

Overidden "Apple style" keys

The "Apple style" scheme of keys can be hard on Lazarus users who work with Lazarus on multiple platforms because many of them are very different from the FreeBSD, Linux and Windows schemes. To minimize this problem the "macOS, Lazarus style" scheme was created (based on the default "macOS, Apple style" scheme, but with some changes to have keys similar to those on other platforms. Below are the keys which differ from the standard "macOS, Apple style" scheme:

Keys Function in Apple style Function in Lazarus style
Home/End jump to start/end of file jump to start/end of line
