Thanks Xue and Rüdiger

So we can change
(setq apl-map1 (make-sparse-keymap))
(define-key apl-mode-map (kbd "<f8>") apl-map1)
(setq apl-map2 (make-sparse-keymap))
(define-key apl-mode-map (kbd "<f9>") apl-map2)

to

(setq apl-map1 (make-sparse-keymap))
(define-key apl-mode-map (kbd "C-c 1") apl-map1)
(setq apl-map2 (make-sparse-keymap))
(define-key apl-mode-map (kbd "C-c 2") apl-map2)

In fact I dont think that either is very convenient anyway.
Ideally it should be a modifier key like AltGr or WinMenu(?).
Something that will be minimally intrusive on rest of emacs and rest
of X and be reasonably portable.

However I could not wrap my head round xmodmap so consider this as an
interim emacsy solution.

How does that work??

Ive used quail like so:
(quail-defrule ".." ?॥)
(quail-defrule "." ?।)

for entering sanskrit text (those two characters are two kinds of
'full-stops' in sanskrit)  But then you cant enter a normal English
fullstop.
This is fine for entirely sanskrit texts.

However here we need the w key to generate sometimes plain ol w ,
sometimes ⍵ sometimes ⌽ .  So some kind of modedness is inevitably
required no??
