These can't come from the profile either; since st opens a new tty that is not the same device the user logged in on. (stty(1)). Backspace key in st generates > BACKSPACE, but almost all terminals generate DELETE instead > (read FAQ for more details). It's not clear why the position of the key and the intent of the user typing it is less important than the label of the key. What's st's position on prior/next/find/select vs pgup/pgdn/home/end? And speaking of the editing keypad keys, the code that most terminals send for the del key is that for the VT220 "remove here" key. The delete key above enter on the VT220 is labeled <x], so it clearly has a meaning of delete left despite sending ^?, and thus establishes an association between ^? and delete left long before linux. The fact that the PC keyboard key in this position is labeled Backspace is the historical accident. > I also have some adittionals > configurations like for example 'tput smkx' (set keypad on), > or `tabs`.About the three variables you tell, TERM is the only > that a terminal must set, LINES and COLUMNS are shell stuff > and are not even standard. Their meaning is defined in the standard. The method of obtaining default values is not, but that means it's the implementation's responsibility, not that it doesn't mean anything at all. But unsetting it, along with the initial call to cresize, should be fine on most systems, so maybe I've been too harsh about this.
