Keyboard shortcuts for Zeppelin Notebook

Question

There was an old jira for keyboard shortcuts. But there did not appear to be an associated document

https://issues.apache.org/jira/browse/ZEPPELIN-391

Is there a comprehensive cheat-sheet for the shortcuts? Especially to compare to the excellent jupyter keyboard shortcuts; e.g. dd to delete a cell.

Here is a table for the shortcuts.

| Ctrl + Alt + m    | toggle showing line numbers       |
| Ctrl + Shift + -  | width - 1                         |
| Ctrl + Shift + =  | width + 1                         |
| Ctrl + Alt + t    | toggle title                      |

Note: Some shortcut might not work depend on OS and browser.

Answer 2

There is a keyboard icon that lists them:

It is is missing some e.g.

ctrl + /         comment whole line
ctrl + shift + / in-line comment
