remember that computers suck.
there you can tell the line editor to turn on "application" mode when it starts and turn it off when it stops: function zle-line-init () { echoti smkx } function zle-line-finish () { echoti rmkx } zle -N zle-line-init zle -N zle-line-finish Putting these lines into your .zshrc will fix the problems. ## How can I use meta in 8bit mode? St supports meta in 8bit mode, but the default terminfo entry doesn't use this capability. If you want it, you have to use the 'st-meta' value in TERM. ## I cannot compile st in OpenBSD OpenBSD lacks librt, despite it being mandatory in POSIX . If you want to compile st for OpenBSD you have to remove -lrt from config.mk, and st will compile without any loss of functionality, because all the functions are included in libc on this platform. ## The Backspace Case St is emulating the Linux way of handling backspace being delete and delete being backspace. This is an issue that was discussed in suckless mailing list . Here is why some old grumpy terminal users wants its backspace to be how he feels it: Well, I am going to comment why I want to change the behaviour of this key. When ASCII was defined in 1968, communication with computers was done using punched cards, or hardcopy terminals (basically a typewriter machine connected with the computer using a serial port). ASCII defines DELETE as 7F, because, in punched-card terms, it means all the holes of the card punched; it is thus a kind of 'physical delete'. In the same way, the BACKSPACE key was a non-destructive backspace, as on a typewriter. So, if you wanted to delete a character, you had to BACKSPACE and then DELETE. Another use of BACKSPACE was to type accented characters, for example 'a BACKSPACE `'. The VT100 had no BACKSPACE key; it was generated using the CONTROL key as another control character (CONTROL key sets to 0 b7 b6 b5, so it converts H (code 0x48) into BACKSPACE (code 0x08)), but it had a DELETE key in a similar position where the BACKSPACE key is located today on common PC keyboards. All the terminal emulators emulated the difference between these keys correctly: the backspace key generated a BACKSPACE (^H) and delete key generated a DELETE (^?). But a problem arose when Linus Torvalds wrote Linux. Unlike earlier terminals, the Linux virtual terminal (the terminal emulator integrated in the kernel) returned a DELETE when backspace was pressed, due to the VT100 having a DELETE key in the same position. This created a lot of problems (see [1] and [2]). Since Linux has become the king, a lot of terminal emulators today generate a DELETE when the backspace key is pressed in order to avoid problems with Linux. The result is that the only way of generating a BACKSPACE on these systems is by using CONTROL + H. (I also think that emacs had an important point here because the CONTROL + H prefix is used in emacs in some commands (help commands).) From point of view of the kernel, you can change the key for deleting a previous character with stty erase. When you connect a real terminal into a machine you describe the type of terminal, so getty configures the correct value of stty erase for this terminal. In the case of terminal emulators, however, you don't have any getty that can set the correct value of stty erase, so you always get the default value. For this reason, it is necessary to add 'stty erase ^H' to your profile if you have changed the value of the backspace key. Of course, another solution is for st itself to modify the value of stty erase. I usually have the inverse problem: when I connect to non-Unix machines, I have to press CONTROL + h to get a BACKSPACE. The inverse problem occurs when a user connects to my Unix machines from a different system with a correct backspace key.
