I have found a strange idiosyncrasy of running Ubuntu on a mac in parallels. A lot of my keyboard shortcuts don’t work. For instance in a browser alt back arrow key doesn’t work. Or in Webstorm alt insert doesn’t bring up the add a file menu.
What I have found, at least for those two is that if you hit the combo twice in succession it actually works. Consistently. Strange but workable. I don’t know how many of the other shortcuts will work if I try this. Ususally just pound on it get frustrated and grab the mouse. I’ll have to be more patient and try. So we’ll see.
