23 * - stuffed characters: A command that is translated into another command.

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().
