OP, you can do this in different ways. But all are dirty.
You can even have pointer to the global varible before declaring
local varible and other different ways: *all bad, forget bout them
all*
What you should be doing is to have a namespce for your global
varible. That's the cleanest implementation I can think of. No issues,
you have to specify which var you are accessing.
btw, "a" is not working on my keyboard, went and purchased a new
Logitech keyboard. Very bad quality, keyboard keeps getting
disconnected, I have to physically reconnect the keyboard every few
minutes. Hfta go get replacement.
Try pasting "a" instead of typing "a", its a BIG pain in the wrong place
