SUMMARY When using the menu only with keyboard, some actions have to be done with space instead of enter. The most obvious example is the power and session buttons, which can be selected pressing space, but not enter. STEPS TO REPRODUCE 1. Use meta key to open the menu 2. Use tab key to navigate through the menu (Applications -> Places -> Power and session buttons) to the power buttons 3. Press enter when selecting reboot, for example. OBSERVED RESULT After pressing enter, the selection is moved to the favorite application list/grid instead of imitating the same action as left click. Pressing space key does work. EXPECTED RESULT Pressing enter should be equal to left click. I would either replace space with enter, or make both do the same.

It's a general problem in Qt; Spacebar is used to trigger the highlighted UI element; while Enter/Return selects items in item views (list views, grid views, etc) In practice this is kind of an arbitrary distinction and people get confused about it. I agree that it would be better if enter/return also triggered the currently-highlighted UI element. Noah has submitted a thing upstream to fix this generically for Qt: https://codereview.qt-project.org/c/qt/qtdeclarative/+/390702 So I'm marking this as an upstream issue for now. If that doesn't get merged, then we can look into working around it ourselves in KDE.
