When the user selects an item and presses Return, their choice is printed +to stdout and dmenu terminates.

It manages windows in tiled, monocle +and floating layouts. Either layout can be applied dynamically, optimising the +environment for the application in use and the task performed. +.P +In tiled layouts windows are managed in a master and stacking area. The master +area on the left contains one window by default, and the stacking area on the +right contains all other windows. The number of master area windows can be +adjusted from zero to an arbitrary number. In monocle layout all windows are +maximised to the screen size. In floating layout windows can be resized and +moved freely. Dialog windows are always managed floating, regardless of the +layout applied. +.P +Windows are grouped by tags. Each window can be tagged with one or multiple +tags. Selecting certain tags displays all windows with these tags. +.P +Each screen contains a small status bar which displays all available tags, the +layout, the title of the focused window, and the text read from the root window +name property, if the screen is focused. A floating window is indicated with an +empty square and a maximised floating window is indicated with a filled square +before the windows title. The selected tags are indicated with a different +color. The tags of the focused window are indicated with a filled square in the +top left corner. The tags which are applied to one or more windows are +indicated with an empty square in the top left corner. +.P +dwm draws a small border around windows to indicate the focus state. +.SH OPTIONS +.TP +.B \-v +prints version information to stderr, then exits. +.SH USAGE +.SS Status bar +.TP +.B X root window name +is read and displayed in the status text area.

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. + + [1] http://www.ibb.net/~anne/keyboard.html + [2] http://www.tldp.org/HOWTO/Keyboard-and-Console-HOWTO-5.html + + +## But I really want the old grumpy behaviour of my terminal + +Apply [1]. + +[1] https://st.suckless.org/patches/delkey + + +## Why do images not work in st using the w3m image hack? + +w3mimg uses a hack that draws an image on top of the terminal emulator Drawable +window.
