/* EEL code file for editing the Interrupt List */
/* */
/* Written by Ralf Brown */
/* LastEdit: 30 Aug 98 */
/* */
/* This EEL file adds the following keybindings: */
/* Shf-Alt-A add an Access: section to the current entry */
/* Shf-Alt-B add another BUG: to the current entry */
/* Shf-Alt-D add a Desc: section to the current entry */
/* Sft-Alt-I add an InstallCheck: section to current entry */
/* Shf-Alt-R add a Range: section to the current entry */
/* Shf-Alt-S add a Size: section to the current entry */
/* Alt-I add an Index: section to the current entry; */
/* add another Index: line if already on Index: */
/* Alt-N add a new note to current entry or data struct */
/* Alt-P add a Program: section to the current entry */
/* Alt-R insert Return: at start of line */
/* Alt-S insert SeeAlso: at start of line; add another */
/* SeeAlso: line if already on SeeAlso: */
/* F11 insert a blank separator line */
/* ^F11 create Format of: header */
/* Shf-F11 create Values for: header */
/* Alt-F11 create Call with: header */
/* Alt-F12 create Bitfield for: header */
/* F12 add the interrupt number to the separator line */
/* preceding the current entry */
/* ^F12 jump to a specified entry */
/* */
/* It adds the following unbound commands: */
/* renumber-tables */
/* make-distribution */
/* filter-region */
/* run region through a specified command; by */
/* default, the program is given the region on its */
/* stdin and its stdout is used to replace the */
/* region; if one or two "%s" are given, they */
/* will be replaced by the input and output (resp) */
/* file the program should use. */
/* */
/* Other: */
/* adds intlist-mode for .LST and .1ST files */
/* switches current buffer into intlist-mode on loading */
/* maintains a table counter which is inserted each time */
/* a table is created in the text */
/* performs syntax highlighting (Epsilon v7+) */
