I've seen this option in one Ubuntu machine and I want to replicate it in my mac:
Hold a Key for 2 second to activate it.
What I have seen is this: Hold down a Key for 2 second (SHIFTShift for example). Then write something and the writewritten text was as if the SHIFTShift key is pressed (and it acts like the Caps LockCaps Lock pressed). PressThen the key is pressed one time forto deactivate it.
Is it possible to achiveachieve this on a mac too?
