![]() Notice how the word is completed to resolution for you. Now go to the very end of the *M2* buffer with M-> and experiment with keyword completion. If you select several lines using the mouse, then pressing f11 will present the entire selection to Macaulay2. Position the cursor on the first line of code, and press the f11 function key repeatedly to present each line to Macaulay2. If you wish, save the file using C-x C-s. ![]() m2 is important, as it informs emacs to use the Macaulay2 mode). Now create (using C-x C-f) a file, named something like foo.m2 (the final. Verify that Macaulay2 is running by entering a command such as 2+2. You may use C-x o freely to switch from one window to the other. Solomon's, which can interfere with emacs when it tries to run a subprocess. A third reason may be that you are in Windows-98 and are using anti-virus software such as Dr. Another reason may be that you have not installed Macaulay2 properly - the startup script ( M2 or M2.bat) should be on your path. If f12 doesn't start up Macaulay2, one reason may be that your function keys are not operable. (The command line used to start Macaulay2 may be edited before being run if you use a prefix argument with the above command: press C-u just before.) Then press the f12 key or type M-x M2 to start up Macaulay2 in a buffer named *M2*. Use the keystrokes C-x 2 to divide the buffer containing this file into two windows. Similarly, C-c means to press the c key while holding down the control key, and C-x 2 means to press x while holding down the control key, then to press 2 this time do not press enter. Sending lines or selected text to Macaulay2 using the f11 keyīefore starting, note that when we say to type M-x M2, what we really mean is: press the x key while holding down the meta key (on Macs this is either the option key or the apple key, depending on how your emacs is set up) type M2 and then press the return (or enter) key after that. Starting Macaulay2 with the f12 key, or with M-x M2 The aspects of this interface that we describe include For the rest of this section, we assume that you are running emacs. emacs file mentioned there, you need to exit and restart emacs. We assume that you have already set up this interface, as described in setting up the Macaulay2 emacs interface. It is more common today to use the Windows key to emulate the Super key.In this section, we show by example how to use the Macaulay2 emacs interface. ![]() Because of these workarounds, the need for Meta – despite being the most-used additional modifier key – was less than for other modifier keys. However, software often provides another workaround, such as using the Alt key (which does not exist on the Knight keyboard), or using the Esc key as a prefix (e.g., in Emacs). On keyboards that lack a physical Meta key, its functionality may be invoked by other keys such as the Windows key or Macintosh's Option key. However, on most modern keyboards, the Control key is farthest from the space bar, reversing the convenience of shortcuts. All these keys produced shortcuts (2 4 of them for every letter), but the Control ones were easiest to type and most popular, and the Meta ones second-easiest and thus second most popular. The space-cadet keyboard added the Super key outside Meta, and the Hyper key outside that. On these keyboards the Control key was placed closest to the space bar, then the Meta key outside Control. 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).
