Hi, as mentioned on https://invent.kde.org/plasma/plasma-desktop/-/issues/102 Nate suggested I add this as a feature request here. Posting from an expiring account due to email addresses being public.
"As someone raised a number of years ago in https://www.reddit.com/r/kde/comments/6a3ntq/keep_task_switcher_open_after_pressing_alt_tab/ the Plasma task switcher doesn't seem to have the option to stay open until a window is selected, which is awkward for people with limited dexterity, one hand, etc. And would presumably be helpful for touch input users too.
Standard keyboard shortcuts mirror the Windows Alt+Tab behaviour, but what Windows also provides is a separate keyboard shortcut (Ctrl+Alt+Tab) to open the task switcher and wait for a selection.
It'd be great if this could be considered."
STEPS TO REPRODUCE
1. Open task switcher with shortcut.
2. There isn't an option or alternative shortcut for the task switcher to remain open until an item is selected.
1. Task switcher closes when shortcut keys are released.
1. Optionally or with a separate shortcut allow the switcher to remain open until an item is selected.
