I won't put this in blue because it's not specifically an ICS tip, but for anyone who hasn't used it, one of the best things about the Swype keyboard is being able to shift into 'edit mode' by swiping to the right over the two bottom-left keys. This displays four arrow keys, select/copy/paste/delete, cursor jump (great to select a large block of text at one time), end, home, forward/reverse delete, etc. This works in any text entry box, so it gives you full editing even in apps (like SMS) that don't provide it or where it's more limited. Frankly, even if I just used Swype for regular key-by-key typing, I'd still want it for this feature alone!
