22 * These buffers are used for storing: | |
23 * - stuffed characters: A command that is translated into another command. | |
24 * - redo characters: will redo the last change. | |
1992 | 25 * - recorded characters: for the "q" command. |
7 | 26 * |
27 * The bytes are stored like in the typeahead buffer: | |
28 * - K_SPECIAL introduces a special key (two more bytes follow). A literal | |
29 * K_SPECIAL is stored as K_SPECIAL KS_SPECIAL KE_FILLER. | |
30 * - CSI introduces a GUI termcap code (also when gui.in_use is FALSE, | |
31 * otherwise switching the GUI on would make mappings invalid). | |
32 * A literal CSI is stored as CSI KS_EXTRA KE_CSI. | |
33 * These translations are also done on multi-byte characters! | |
34 * | |
35 * Escaping CSI bytes is done by the system-specific input functions, called | |
36 * by ui_inchar(). | |
37 * Escaping K_SPECIAL is done by inchar(). | |
38 * Un-escaping is done by vgetc(). | |
