Yes, in Xy4 it's used in both contexts, with completely different
results. A lone Q2 (usually assigned to F2 in the .KBD file)
suspends spell-checking. After BX, it executes a command. A
syntactical oddity, to be sure.

Actually, the routine is Robert Holmgren's, and the "Ascii
equivalents" (5-byte analogs) of both BX and Q2 are right there, in
plain view, in the code. The effect of  after each of these
strings is to translate the 5-byte string into the corresponding 3-
byte string (the embedded function). (The byte-level content of
func BX is the same whether you're viewing it in Xy3 or Xy4; it just
looks different, and, of course, has no functionality, in 3.)

By the way, the Jumbo U2 command to see the underlying byte content
of any 3-byte character is (with the cursor on the character):
V3. If the cursor is on a 1-byte character, it returns the
Ascii number.
