Created attachment 139675 [details] panel indicator SUMMARY First of all let me stress out that using gestures is not full-proof like using keyboard. It is more like hit and miss situation, so visual confirmation is imperative. Imagine you have entered command in konsole and you've been given no output. Usually, this is achieved by leaving a mouse trail on screen as suggested in future-request https://bugs.kde.org/show_bug.cgi?id=135097. Now, I'm aware this may be difficult to implement in Wayland session. Nevertheless, this or any other confirmation is way better than none. E.g. Easystroke have a panel indicator as shown in the attachment.
As announced in https://pointieststick.com/2023/07/26/what-we-plan-to-remove-in-plasma-6/ and https://community.kde.org/Plasma/Plasma_6#Removals, I'm afraid KHotKeys has reached end-of-life in Plasma 6. Accordingly, all bug reports and feature requests for it must be closed now. Most of what KHotKeys could do can already be done with the newer KGlobalAccel system in Plasma 6. A few features such as mouse gestures and triggering conditions based on changes to window states are not yet implemented in the new system. These will be added in the future if and when resources materialize for them, and/or when a kind soul submits patches to implement them! :) Meanwhile, the 3rd-party "Mouse Actions" app (https://github.com/jersou/mouse-actions) may be usable for implementing your own mouse gestures again. Thanks for your understanding, everyone.
