And I thought that I knew a fair bit about computers.
Thanks hc, I have tested what you have said and 'Escape' is a quick one for use on You Tube to reduce the size of picture, furthermore I understand that it will act as a 'pause button' if one is playing an 'on-line' computer game. (Something I never do )
It would be interesting to know the type of 'Full Screen' from which both boxtops and ummmm are escaping :-) Also a further comment from Buenchico would be interesting. ☺☺☺
