The Model M is bulky, noisy, and massive, but when it comes to entering characters into a computer, it can’t be beat. Issues of logical design, You can either define a new physical keyboard layout by looking at definition of quail-keyboard-layout-alist in quail.el or create a new input method by defining corresponding Arabic keys for Dvorak layout. https://upload.wikimedia.org/wikipedia/commons/0/0b/ASR-33_2.jpg, [source: https://news.ycombinator.com/item?id=3684515 (local copy hackernews_why_vi_terminal_adm_3a_uses_ijkl.txt )], See also: All these keys have become de facto standard on all applications on {Windows, Mac, Linux} today, except the Ctrl+Shift+z for redo and D for Duplicate. : key. The CTRL-H, J, K, L therefore correspond to BS, LF, VT, FF. A Curious Look at Emacs's One Thousand Keybindings, http://groups.google.com/group/comp.emacs/msg/0342e0bc1aa05c0d, Lisp Programer Daniel Weinreb Died (1959 to 2012), https://vintagecomputer.ca/lear-siegler-adm-3a-terminal/, https://upload.wikimedia.org/wikipedia/commons/0/0b/ASR-33_2.jpg, https://news.ycombinator.com/item?id=3684515, hackernews_why_vi_terminal_adm_3a_uses_ijkl.txt, Emacs vs vim, Compute Keybinding Efficiency, Apple Macintosh Keyboard (M0110) (year 1984), Control Key and Capslock Key Positions in Old Keyboards, Difference Between Apple and PC keyboards, Backspace Key: Key Label's Influence on Key Purpose, Print Screen, SysRq, ScrLk, Pause, Break Keys, https://news.ycombinator.com/item?id=6056420, https://news.ycombinator.com/item?id=14367207. Right hand is the more dexterous hand for most people, and operating the mouse needs more dexterity than pressing arrow keys. For emacs users out there, what are your recommended keyboards? Some Emacs command sequences are just one character or one event; for example, just C … Some of the non-printable And when you see a ^@ being printed on the terminal you can see why it corresponds to a null byte. Emacs's keybinding is not simply based on the first letter of commands, but the QWERTY layout's key positions have significant influence on it. To avoid problems I shamelessly copied the emulate-mac-keyboard.el from the Aquamacs project, modified it a little bit and now using it. ergonomics, consistency, efficiency, are less important. I'm not sure why FF was used for up [right]. To really know, one must read the character by some choice interpretation corresponds to arrow directions, and the corresponding The original poster has implied that Emacs is receiving the keyboard input of Command+ALT+-, which Emacs responds to by displaying a message M-s-- is undefined. It is a key on Lisp keyboards. (like how Microsoft Windows's Alt key works (from about Windows 95 to Windows 7).) [5] Each group was in a row, thus allowing easy chording, or pressing of several modifier keys; for example, Control+Meta+Hyper+Super could be pressed with the fingers of one hand, while the other hand pressed another key. As a example, emacs's Meta key, and heavy use of Ctrl as primary modifier, and avoiding any Ctrl+Shift+letter in its keyboard shortcuts, are caused by the lisp keyboard hardware and dumb terminals of 1980s. S-7 gives the '/' character). The keyboard on lisp machines have the Ctrl key besides the space bar (similar to the position of Alt keys on PC keyboards), and Meta to the left of Ctrl . ; Alt keys that are closer to the centre, and easier to use with meta key combos. This rivalry goes back to pretty much before there was even an Internet. In retrospect, many of the choices are not the best today. For example, if set as true, when you type C-a, the cursor moves to the beginning of the line (Emacs' original behavior). This is also why CTRL-I is tab, CTRL-D ends a communication. In Apple's operating system, in Mac Classic of the 1990s or Mac OS X since early 2000s, this key was not used for browser's back function, only so around ~2006 when Apple started to adopt many Windows's conventions. You can now also give it a keyboard shortcut, such as F8. ‘C-e’ (or ‘M-x end-of-line’) to move the cursor to the end of the line. Keywords Lambda Calculus ASCII Character ASCII Code File Menu Shell Command These keywords were added by machine and not by the authors. Once the extension is installed you should be able to use familiar keyboard shortcuts to execute Emacs commands within Visual Studio. The master configuration file 'emacs.org' in that repository claims: On OS X the keyboard is a little bit fucked up when using Emacs. If you are a emacs user, the optimal position for Ctrl is the 2 big Alt key on Microsoft Ergonomic Keyboard right under your thumbs, 2 of them, symmetrically placed, pressed by a strong finger thumb. Major keyboard makers Microsoft and Logitech have started to make keyboards with these functions pre-assigned to the F1 to F12 Function keys. emacs-mcx.strictEmacsMove. https://news.ycombinator.com/item?id=6056420. Authors; Authors and affiliations; Harley Hahn; Chapter. These form the library of Emacs input methods, required to type international characters that can't be directly produced by your keyboard. As a result of Emacs making frequent use of multiple modifiers, which are easy on the space-cadet keyboard, it is substantially harder to use on modern keyboards, whose layout generally follows the Model M IBM PC keyboard, where the modifier keys are not grouped together and thus are harder to press together. The Emacs Editor's keyboard stickers are ideal for all users, for beginners as well as professionals. It was inspired by the Knight keyboard, which was developed for the Knight TV system, used with MIT's Incompatible Timesharing System.
