Add ability to comment line with a shortcut

Add keyboard shortcut to comment out one line. For example, in PyCharm you can use command + / key combination on mac to comment one line.

Hi Andrew,

This improvement is already planned - I’ll post an update when it will be implemented.

Anyway, thanks for the feedback!

Hello again!

I am glad to say that the requested feature was implemented some time ago. Please note that commenting of compound statement isn’t supported yet.
