Certains keys (such as ~ and |) are in the keyboard map behind the second shift level. This means in order for them to be input, the shift key needs to be held down by the user. The GNOME Shell on-screen keyboard presents these keys separately on a page of keys that has no shift key. Instead, it relies on mutter to set a shift latch before the key event is emitted. A shift latch is a virtual press of the shift key that automatically gets released after the next key press (in our case the ~ or | key). The problem is using a shift latch doesn't work very well in the face of key repeat. The latch is automatically released after the first press, and subsequent repeats of that press no longer have shift latched to them. This commit fixes the problem by using a shift lock instead of a shift latch. A shift lock is never implicitly released, so it remains in place for the duration of key repeat.

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.

Git messages
Commit messages should follow the GNOME commit message
guidelines. We require an URL
to either an issue or a merge request in each commit. Try to always prefix
commit subjects with a relevant topic, such as compositor: or
clutter/actor:, and it's always better to write too much in the commit
message body than too little.
Default branch
The default development branch is main. If you still have a local
checkout under the old name, use:
git checkout master
git branch -m master main
git fetch
git branch --unset-upstream
git branch -u origin/main
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
