second keyboard for sketchup

[thegoogler]

hello has anyone followed taran's guide to setting up macro keys? because I have a problem where he is using his for premier I want top use mine for sketch up just so that I only need to press one key and can label them so that i remember. but I can't seem to get only one keystroke when I try and set a function for a key (this is bad because sketch up can only use 2 keys in a combination), if i press shift as fast as i can it will still say it is 2 key presses therefore putting down 2 shift which then i need to restart mapping that key. if someone know how to fix this that would be great. If I am just stupid and haven't realized that I need to do other stuff to get it working please tell me but my thinking is that I programe the keys then when I open sketch up and I press that key that it will just execute the key stroke? am I wrong in thinking this? someone please help.
