On my 48SX I can swap a number that has not been entered onto the stack with a number already on the stack just by using the swap key.
On the 49g+ I have to go through "tools", "stack", then "swap", or enter the number on the stack with the number to be swapped and then hit the right arrow key.
Is there another way to make the 49g+ swap like the 48SX without having to go through all this?
