One of the nice things about Dyalog Apl is an on screen keyboard.
I have different settings for my keyboard and sometimes it can be a
bit confusing to know which one is active.
I switch between DE,FR,SW,IS,EN and then within those there are
others.
With the on screen keyboard it is quite easy to mix using the mouse
and/or the keybord and the on screen keyboard will show waht is being
produced.
It would be possible to have stickers for all of the combinations of
meanings of the individual keys.
And now that Unicode is being supported these keys can have individual
meaning and coexist.
I have to say that APL has come a long way since I took a pause using
it.
It is quite a task of relearning old features not to mention all the
new features that have been added while I was not looking.
