Subject: Esc now acts as a latch for the Start key (irssi-like, plus easier
 for XEGS/1200XL users).

 Other stuff:
 
+- Make ctrl-insert toggle between insert and typeover mode (The_Doctor__).
+- Make control + 1 through 7 switch windows (same as Start), because
+  the XEGS and 1200XL Start keys are hard to reach while typing (brad
+  and MarkG).
+- Also, make Escape a "start key toggle". Not only XEGS and 1200XL will
+  benefit: I *still* catch myself trying to type Esc+Number or Esc+A
+  because Irssi uses that.
+- Filter out the rest of the keystrokes that causes cgetc() to block.
+  Includes ctrl-/, ctrl-8, ctrl-9, maybe others (The_Doctor__).
+- Disable the Break key. It doesn't seem to hurt anything when you
+  press Break, but it makes the edit window disappear for a split
+  second.
 - Stop using ASCII translation on the FujiNet. It's turning a outgoing
   ~ into a ^H (since ATASCII's backspace is DEL in regular ASCII). In
   theory IRC servers always send us \r\n, we can support non-conforming
   servers that just use \n without much trouble, too.
-- Load/save config files to N:SD//.FujiNetChat or such. Since we *have*
+- Load/save config files to N:SD///.FujiNetChat or such. Since we *have*
   to have a FujiNet anyway, might as well make better use of it.
 - Rewrite the incoming message parser! It needs to work more like
   the command parser in cmd.c: know how many arguments to expect, and
