No they already have underlines and access to them via the alt + underlined letter. I mean the fetch metadata from the server button and the fetch cover image from the server button. - I find when updating the information I get stuck and have to use the mouse. The real reason i ask is I want to use you program as a method of allowing disabled users to access the program using other methods such as a button or switch.
I also notice that even tho you can use the right click keyboard button you cannot actually use the letter as a method of accessing the option you have to use the arrow keys.
But I still think your program rocks
As for the switch I would love to be able to get that to work on the 505 but at the moment with the software being locked down its just beyond me
