Here the whole list of ANSI escape sequences can be found. I cannot simply keep pressed and hit a few s.
TEST FOR ANSI ESCAPE SEQUENCES PLUS
(The plus sign is actually superfluous in this case, if not incorrect, and the keystrokes should be written simply as. So a sequence such as + needs to be entered by typing the key, and then typing the key.
It is not a modifier key like the, , and keys. The key is a key that generates a (control) character. if I press, this guy is received as meta! On these keyboards you could get many commands per letter by combinations of Meta with other modifier keys such as Hyper and Super. Generally the Meta key worked similar to Macintosh's Command key, in that when held down it modified letters and symbols into immediate commands (shortcuts). The Meta key is a modifier key on certain keyboards. On Teletype terminals only a few such key combinations generated actual character codes.Īpparently this option you describe is to replace the functionality of the key. On PCs compound modified keys can be defined, i.e. You seem to be describing such a nonstandard, customized handling of keyboard scancodes. That means that the previous comments on how the, , and keys behave on a standard terminal may not apply in all cases.

It is up to software to translate and remap the keypresses.

On a PC the keyboard hardware generates scancodes so that every keypress (and release) can be detected. The reasons is received as meta- is because I've checked "Send Alt as Meta" in Terminal.app settings. Whereas + generates an ASCII SOH (start of header) character. Without the modifier key, a low-case a character would be generated.
TEST FOR ANSI ESCAPE SEQUENCES CODE
The modifier key can generate a unique character code based on the type key.įor instance + generates an upper-case A character. Note that (contrary to your assumptions), a modifier key does not necessarily prepend characters to form an escape sequence. When I press these keys, the program thinks I'm pressing +, instead The plus sign, +, as used in this notation indicates the key combination, and does not indicate a key that should be typed or pressed as a keystroke for this combination. press and release) the, and then release the. The notation means that you should hold down the, type (i.e. The notation used for describing such a combination of keys is: + These keys generate an alternate character code when combined with another key. The, , and keys do not generate any characters (by themselves). Key concepts about standard terminal keyboards: These are "bindings" between keystrokes and. I'm wondering now what sequence should be sent when + is pressed instead. This answer points out that sometimes it's necessary to enforce Mac's Terminal.app to send correct escape sequences, and precisely as \033[5~, which it's what is already happening on my machine. The two-byte code for the key is 0x0 0x49 or decimal 0 73.ĭo you understand what [5~ may refer to, then? The key is not a modifier key, and should not be kept "pressed". I'm wondering whether MacOS caught that key combination and did send something else to my terminal, like that +. I indeed did "hold down the key, type the key, and then release the key". If the program responds as if you are "pressing + ,", then you apparently did something else. So did you hold down the key, type the key, and then release the key? You seem to be misunderstanding the required keystrokes and which keys generate characters. So, I'm not sure what's going on in this website as well. Strangely, seems to be encoded as 0 73, and not the expected [5~. I'm sitting on a Mac, using Terminal.app, ssh-ing into a CentOS, connected to a tmux session, running WeeChat in one window. + is escaped incorrectly (?) as meta-meta2-5~.+ is escaped incorrectly as meta-, (should be meta-meta2-5~).(I cannot simply keep pressed and hit a few s. Now (hold on for such strange behaviour), if I press, this guy is received as meta! So, to scroll up a few lines I can press + a few times. (Typing +, is also received as meta-, so it is my understanding that corresponds to meta here.) The reasons is received as meta- is because I've checked "Send Alt as Meta" in Terminal.app settings. Typing + is received as meta-, instead of meta-meta2-5~. (So, it is my understanding that meta2 is [.) This works fine and represents the escape sequence: [5~. In my terminal, typing is received as meta2-5~.
When I press these keys, the program thinks I'm pressing +, instead. To scroll a few lines up in WeeChat one is supposed to press +.
