tab+1

[m1nuz]

in the new update now for some reason you can't bind tab+1 to upgrade a skill.

I used to be able to do that last night, but today, for some reason; I cannot bind TAB + [Key]. Shift and ALT both work, but not tab.
Please revert as soon as possible.

As of today, Tab + 1,2,3,4 upgrades the respective abilities
