The workstation binds actions to the arrow and home/end/etc keys, using both the keypad (KP_) names and the non-keypad names. On macos laptops, these used to be accepted, but at least with macos 11.4, it now fails because the KP_ names are not found. If these keys do not exist, that is fine, so we can guard the call with catch (noting that try is not available until tcl 8.6). It'd be nicer if we could test explicitly whether the key exist, and skip the bind -- at the moment, if the bind fails for an unexpected reason, we are silently ignoring it.
