What unicode code point?» character: ☄ (299364, #o1110544, #x49164, U+2604) Name: COMET you might want to install the unicode data file so these info and more is available to what-cursor-position (Ctrl+u Ctrl+=). (I append the char to end of my sig to force web-based forums to use unicode for encoding.) See: http://xahlee.org/emacs/emacs_n_unicode.html quote: Q: I have this character α on the screen. How to find out its unicode's hex value or name? You can find out a character's decimal, octal, or hex values by placing your cursor on the character, and type “Alt+x what-cursor- position” (Ctrl+x =). You can get more info if you place your cursor on the character, then press “Ctrl+u Ctrl+x =”. However, if you want the complete unicode info of a character, you need to download a unicode data file and let emacs know where it is. The unicode data file can be downloaded at: http://www.unicode.org/Public/UNIDATA/UnicodeData.txt. After you downloaded it, place the following code in your “~/.emacs” to let emacs know where it is: ; set unicode data file location. (used by what-cursor-position) (let ((x "~/Documents/emacs/UnicodeData.txt")) (when (file-exists-p x) (setq describe-char-unicodedata-file x))) Then restart emacs. Once you've done this, then place your cursor on a unicode char, and do “Ctrl+u Ctrl+x =”, then emacs will give you all the unicode info about that char, including the code point in decimal, octal, hex notations, as well the unicode character name, category, the font emacs is using, and others. For example, here's the output on the character “α”: character: α (332721, #o1211661, #x513b1, U+03B1) charset: mule-unicode-0100-24ff (Unicode characters of the range U+0100..U+24FF.) code point: #x27 #x31 syntax: w which means: word category: g:Greek buffer code: #x9C #xF4 #xA7 #xB1 file code: #xCE #xB1 (encoded by coding system mule-utf-8-unix) display: by this font (glyph code) -apple-symbol-medium-r-normal--14-140-72-72-m-140-mac-symbol (#x61) Unicode data: Name: GREEK SMALL LETTER ALPHA Category: lowercase letter Combining class: Spacing Bidi category: Left-to-Right Uppercase: Α Titlecase: Α There are text properties here: fontified t Xah ∑ http://xahlee.org/ ☄ ^ permalink raw reply [flat|nested] 6+ messages in thread

It makes reading much easier. > am pretty sure that global-set-key cannot be used for the > functionality of keyboard-translate. In a way it can. You can bind it to a macro: (global-set-key "\M-y" "\M-\t") Using `keyboard-translate' is generally a little risky, because it will change the key in all places. So people wouldn't be able to do use C-c M-y anymore. So I would only use it to fix keyboard issues. You can also write a function like this: (defun do-what-backspace-does () (interactive) (call-interactively (key-binding "\C-?"))) I've found that one to be the most reliable solution. regards, Nikolaj Schumacher ^ permalink raw reply [flat|nested] 6+ messages in thread

For example, after i did that, then in a text mode i have cursor at the end of “m” in “this form that”. Then, pressing Alt+y gives me this error: «After 0 kbd macro iterations: ispell-command-loop: Keyboard macro terminated by a command ringing the bell» but pressing Esc Tab does return a list of completion. what i'm trying to do is to get command completion to some Meta +‹letter› binding, because Alt+Tab is used by the OS to switch apps. So, in the past 10 years i just used Esc Tab but that's 2 keystrokes... The normal way of binding M-‹letter› to a command wont work well because the command name varies depending on the mode. e.g. ispell- complete-word, lisp-complete-word, etc. > Using `keyboard-translate' is generally a little risky, because it will > change the key in all places.

This won't work for my need above... but will try it out for other uses. Thanks. Andreas Politz wrote:: > (define-key key-translation-map [?\M-y] [?\M-\C-i]) this seems to work. Thanks.
