Tools pallet dropping in single controller data

[xxrich]

Thought I'd ask as the fact that I don't know or it hasn't been obvious to me - might be of worthy value to code developers.

I always want to change a controller value and select the pencil tool.   I would expect a single click to drop a value in., but no, I have to scroll it - then switch tools and delete the un-needed points put in else my already overdriven mix freaks out:-)  So how to drop in a single point?  If easy - it is not intuitive as I've been doing this in my current process for years.    My expected way of it happening is not happening. ?
