JN7 Hotkey "Alt-G" mapped to "Go To Line" clashes with "@"-sign on macOS

[burnpanck]

It appears that JN7 introduced a keyboard short-cut whereby typing "Alt-G" in a code cell will bring up a small "Go to line" input at the bottom of the cell. Unfortunately, that short-cut prevents macOS users (at least with a swiss keyboard, but very likely most western keyboards) from typing an "@", which uses that same short-cut.

That short-cut does not appear in the short-cut list in Jupyter's settings dialog, nor in the "Show Keyboard Shortcuts" dialog accessible from the help menu within the notebook.

Thanks @burnpanck for reporting.

Since Notebook 7 uses the same shortcuts as in JupyterLab, would you be able to check if this is also an issue in JupyterLab? If so we should also report it there, so it at least shows in the list of shortcuts, or maybe suggest to change it?

Indeed, the same issue also appears when editing notebooks from within jupyter lab. It does not appear when editing other documents in jupyter lab (verified on a markdown document).

Thank you for submitting this issue @burnpanck! There is already an issue jupyterlab/jupyterlab#7704 in the Jupyterlab repo, so I will close this one as a duplicate. Please feel free to add to that discussion!
