The action "Edit: Move event left/right (mousewheel/MIDI relative only)" is useful for making small adjustments to selected events. Assign it to a mousewheel shortcut, such as alt+mousewheel.
To further lower the number of clicks, you can select all keyswitch notes by right-dragging the keyswitch range on the piano roll's keyboard, and then moving them all together.
But warning: sequencing music in a DAW is all about surgical editing of MIDI!
If you want to avoid keyswitch notes altogether, perhaps try the
Rearticulate articulation manager.
