30 | ;; This package emulates the mark, copy, cut and paste look-and-feel of motif |
31 | ;; programs (which is the same as the MAC gui and (sorry for that) MS-Windows). | |
32 | ;; It modifies the keybindings of the cursor keys and the next, prior, | |
33 | ;; home and end keys. They will modify mark-active. | |
34 | ;; You can still get the old behaviour of cursor moving with the | |
35 | ;; control sequences C-f, C-b, etc. | |
36 | ;; This package uses transient-mark-mode and | |
37 | ;; delete-selection-mode. | |
38 | ;; | |
13f5a20e | 39 | ;; In addition to that all key-bindings from the pc-mode are |
215e89e5 RS |
40 | ;; done here too (as suggested by RMS). |
41 | ;; | |
42 | ;; As I found out after I finished the first version, s-region.el tries | |
43 | ;; to do the same.... But my code is a little more complete and using | |
44 | ;; delete-selection-mode is very important for the look-and-feel. | |
45 | ;; Pete Forman <pete.forman@airgun.wg.waii.com> provided some motif | |
46 | ;; compliant keybindings which I added. I had to modify them a little | |
47 | ;; to add the -mark and -nomark functionality of cursor moving. | |
48 | ;; | |
49 | ;; Credits: | |
50 | ;; Many thanks to all who made comments. | |
51 | ;; Thanks to RMS and Ralf Muschall <prm@rz.uni-jena.de> for criticism. | |
52 | ;; Kevin Cutts <cutts@ukraine.corp.mot.com> added the beginning-of-buffer | |
53 | ;; and end-of-buffer functions which I modified a little. | |
54 | ;; David Biesack <sasdjb@unx.sas.com> suggested some more cleanup. | |
55 | ;; Thanks to Pete Forman <pete.forman@airgun.wg.waii.com> | |
56 | ;; for additional motif keybindings. | |
14dacacd RS |
57 | ;; Thanks to jvromans@squirrel.nl (Johan Vromans) for a bug report |
58 | ;; concerning setting of this-command. | |
83d1d58c | 59 | ;; Dan Nicolaescu <done@ece.arizona.ro> suggested suppressing the |
20c5a87d | 60 | ;; scroll-up/scroll-down error. |
b50c87ee | 61 | ;; Eli Barzilay (eli@cs.bgu.ac.il) suggested the sexps functions and |
13f5a20e | 62 | ;; keybindings. |
215e89e5 RS |
63 | ;; |
64 | ;; Ok, some details about the idea of pc-selection-mode: | |
65 | ;; | |
66 | ;; o The standard keys for moving around (right, left, up, down, home, end, | |
67 | ;; prior, next, called "move-keys" from now on) will always de-activate | |
68 | ;; the mark. | |
69 | ;; o If you press "Shift" together with the "move-keys", the region | |
70 | ;; you pass along is activated | |
71 | ;; o You have the copy, cut and paste functions (as in many other programs) | |
72 | ;; which will operate on the active region | |
73 | ;; It was not possible to bind them to C-v, C-x and C-c for obvious | |
74 | ;; emacs reasons. | |
75 | ;; They will be bound according to the "old" behaviour to S-delete (cut), | |
76 | ;; S-insert (paste) and C-insert (copy). These keys do the same in many | |
77 | ;; other programs. | |
