is there a way to bind key for shop tavrens?

[salih]

can I somehow make "spacebar" and additional "4th or 5th button of mouse" be a shortcut to shop tavrens?
I know that I can bind them with ctrl + 1 and etc but it doesnt work for space bar. I alreaddy have 1-2-3.. binded with inventory

not unless you use something like AHK, changing the binding of some numerical number to space
