How do I give resources to my teammates, quickly, in Starcraft 2?

Usually, due to my wretched management (or sometimes due to a mass OC strategy), I have a lot of unused minerals.

I understand that one of my primary goals is "to keep money low", but sometimes during team games it would be better if I passed 1-2 thousand resources to my teammates, who seem to be better than me.

When I open the "Money transfer" window, I can increase the amount of resources to transfer by 50 by clicking on the arrows. This is very slow: I could waste 10 seconds clicking those numbers.

Is there any way to quickly increase the number of resources to transfer?

Thanks a lot.

Solution 1:

Holding CTRL allows you to do this in steps of 100 instead of 50.
