Actual it is a Danish keyboard which you can see here
http://en.wikipedia.org/wiki/Keyboard_layout#Danish but many other keyboard layouts have similar issues.
Apparently no programmers were in the commitee that decided on these keyboard layouts
The blue symbols (in the link) are produced by using Right Alt aka Alt-Gr only. Using Left Alt will produce other codes like on US-keyboard: Left Alt-9 is Alt-9 and not }.
This all functions ok in SlickEdit.
However when I press Left Alt
and Left Ctrl simultaneously it has the same effect as pressing Alt-Gr alone in Windows eg. {[]} was produced in this window by pressing LeftCtrl and LeftAlt while keying 7890 !
This does not work in SlickEdit and that is a pitty because it is much easier to key in parentheses using the latter shift keys (using left hand) than using Alt-Gr.
Thanks
