REQUEST: ? toggles Action List show/hide

My request disclaimer got really long so I've moved it to the bottom of my post ↓ Is it possible to make the "?" opening/showing the Action List also be able to toggle it closed/hidden? MY REQUEST DISCLAIMER: I'm still quite new to Reaper, and this is the first time I've made a request here. I've tried to ensure that the following requests aren't things that can already be done in Reaper (with more learning!). Also, I have no idea (yet) what can be done via ReaScripts and what's off the table, and have little understanding of what things can be done quickly and what things will take a lot of time. If any of my ideas/requests are in any way out-of-line just let me know. I do a decent amount of video editing as my job so I understand thoughts of "nobody freakin' understands how long that request takes!". Lastly I'm not against paying for these services . . . I don't have a lot of money but I like compensating people when they help me/others/the community.

Press Esc key to close the window. there is no action to close it. And the problem is also that when you open it, then the keys are used to type the filter

Thanks. I'll just get used to using ESC. ;)
