app/vmui: comment shortcut key and syntax highlighting support

[chenlujjj]

• Without shortcut key, it's not very convenient to comment for multiple lines
• Syntax highlighting can help identify typos and other syntax errors when editing

1. Do you mean the absence of a keyboard shortcut for commenting multiple lines (for example, Alt + /)?
2. At the moment, we are not planning to add syntax highlighting.

Hi @Loori-R

Yes.

The web UI for VictoriaLogs supports Ctrl+/ toggle for commenting the current line in the query input field, starting from the release v1.45.0. Closing the feature request as addressed.
