All puzzles aren't the same, however.
One of the big differences between certain puzzles is how you switch from ACROSS to DOWN and viceversa. On some this can be done with the NESW arrows. But on others, the arrows do not do this, but instead, the BAR.
Is there some kind of add-on to make a key near the arrows change the puzzles direction?
The puzzles that operate using the arrows can be played with one hand. The ones using the bar, two hands.
What's more annoying, is if you play enough of both types, you get them mixed-up from time to time; hitting the bar when you don't have to, or hitting an arrow when it should have been the bar.
Any of the keys on the far right pad would be excellent candidates to enable 'across to down' and 'down to across'.
Maybe there is already a default option hidden somewhere on the OS. I'm running W7.
Thanks to any other Xword nuts.
