For some reason, only the Drop Shadow effect has a keyboard shortcut. So if we frequently use an other effect, we can reacht the effects panel by choosing the keyboard shortcut for Drop Shadow. But then we have to first switch off the Drop Shadow effect.
Why not create a Shortcut to the effects panel, without activating Drop Shadow.

[more: the shortcut currently adds a Drop Shadow AND opens the panel, which is inconvenient if you (for some reason ;-) want to use Drop Shadows all the time.]

Needs a UX rework.
