Keyboard axis restraint hotkeys or keyboard shortcuts for the same.

I have posted this elsewhere..but this might be the correct place?

What I would like to buy...
A tool that gives me , with keyboard shortcuts, the ability to constrain an axis during translate procedures.
I don't mind draggin' the mouse afterwards...it's just selecting the axis...

Clicking on arrows to select an axis is sometimes horrible and inconvenient.
So a tool or whatever to allow users a keyboard shortcut or hotkeys equivalent to the axis arrows?
Anyone willing?
EDIT...Or can this be done already?
