Screen array problem (repost)

I've put together a screen which basically shows seven days of clocking information. I've used a screen array where the rows go down the screen instead of the usual across i.e. MON TUE WED THU [f000 ][f000 ][f000 ][f000 ] [f001 ][f001 ][f001 ][f001 ] [f002 ][f002 ][f002 ][f002 ] [f003 ][f003 ][f003 ][f003 ] [f004 ][f004 ][f004 ][f004 ] Now if the cursor is in field 'mon f0000' and I press TAB or the right arrow, I should want it to go into the tue f000. Instead it goes into mon f0001. This is of course correct if it was set out as normal, f000 to the left of f0001. But in this case it isn't. If the cursor is in wed f003 and I press the left arrow, I want it to go into f003 tue, but it goes into f002 wed (upwards). I just wondered if it's possible to redefine the arrow keys within the program. Or maybe code a way around it. Please help! Thanks, Rich. http://www.netcomuk.co.uk/~richh
