I am an employee and not a volunteer, though I’m unusual in that I’m also a Sage, and so come here after work hours to check for anything I can help on.
There are a few shortcut issues that we’re trying to fix. One is when you are using a non-Roman keyboard, Russian for example, and hardly any shortcuts work, not even the ones for the built in tools.
Another one does involve certain characters, including /. It may not matter what other key is involved, and so /, shift-/, alt-/, may all be failing.
Yet another case is where numeric keypad keys don’t work.
We’re making good progress on most of those variations. I can’t tell you yet when a fix will be in an update, but I will try to come back as soon as there is some news.
