Where is the show key on the nortel T7316 phone
Not sure what you mean by Show key but if it's to check what the buttons are programmed for, you do this:
-press Feature button (strange satellite/orbit button above the Off Hook/Pick up red button on right)
-press *
-press 0
-then press button you want to check
If that's not what you are looking for, give more details what you want to do
