Sorry for the obscure issue but I can't figure out how to get Slickedit (SlickEdit Pro 2018 (v23.0.0.11)) to let me enter a backslash character on MacOS when using a Japanese keyboard.
Note that this is a known issue in general. A Japanese keyboard doesn't have a backslash key but it has a yen key which occupies the same codepoint in Shift-JIS left over from the 80s.
In any case the OS itself has options for this
As does the Google Japanese IME
But Slickedit is apparently going lower-level than these and so is still inserting the yen symbol unlike all the other apps.
Of course it would be great if you could fix this inside slickedit but is there some simple workaround I could use like some how going into the key bindings and assign Â¥ to insert \? There doesn't appear to be a way to do that in the keybindings UI but maybe a short script or something? As it is I end up having to type a / in the terminal and copy and paste into slickedit which is making it pretty hard to edit code 😅
