Change in how the palettes work

Lets take an example

I want to remove staccato, means i have to hit the small point with mouse (difficult), then delete. This becomes frustrating when I tune the flow of music, experimenting this and that.

I thought that the palettes, in cases where applicable, could work like on/off switches. I hit the note(s), then a palette action A, and the property A on the note(s) turns on if currently off and wise versa.
