I have several 'Send Keyboard Input' custom shortcuts that work in Mga5 but do not work in Mga6 (KDE 5.8.7)
In Mga6 KDE go to System settings/shortcuts/custom shortcuts. Open the "Examples" section and select "Type "Hello"" The trigger for this shortcut is CTRL+Alt+H and the action is "Shift+H:E:L:L:O". If you put a checkmark next to "Examples" and "Type Hello" and then press "Apply" that shortcut should be activated. If you open some program that takes keyboard input (konsole or kwrite) and press CTRL+ALT+H it should type "Hello", but it doesn't.
Other shortcuts, like the ones under "Screenshots" do work but not ones that "Send Keyboard Input". I have cauldron running in vbox and keyboard shortcuts work correctly in KDE 5.10.4. I've searched bugzilla and Google but found no info. Will Mga6 be getting an update to fix this problem? Should I put in a bug report?
