Hello. Using Plasma 5.12.7 on Kubuntu Bionic. KWin provides "Switch to next/previous desktop" actions separate from "Walk through desktops" and "Walk through desktops (reverse)" actions. However Plasma does not likewise provide "Switch to next/previous activity" actions. So it is currently not possible to assign shortcuts to them. Thus I request to provide these actions.
by actions you mean keyboard shortcuts?
Yes. It is my understanding that under the Qt/KDE framework Actions are created and then they can be assigned shortcuts. If that is not then please ignore the word usage. All I want is to be able to assign shortcuts.
This has been tried in the past, but a complication is that activities re-arrange themselves based on recency of use, so it would not be predictable as to what activity would be switched to when you used these shortcuts.
You can define shortcuts that traverse activities in alphabetical order here: System Settings -> Shortcuts -> Plasma -> Switch to Next Activity and Switch to Previous Activity Mind that these switch activities without the 'alt+tab' effect of showing the activity switcher. The shortcuts 'Walk through activities' traverse them in most recently used order.
Oh hey, so there are! I didn't notice them because I was looking in the Activity Manager entry, not under Plasma.
