Feature Request: Insert selected text as context in Chat

[Stephen-S-H]

OS version: Mac Sonoma 14.5
Editor version: VS-code 1.92.0
Programming language: any
TabNine extension version: 3.135.0
Feature request:

I often need to copy and paste logs and other data from the terminal into Tabnine Chat. It would be very helpful if there was a way to streamline this. Perhaps a keyboard shortcut that would allow me to add selected text as context, from anywhere in VSCode. It could insert a placeholder in the Tabnine chat message similar to the @filename method, and send the text block to the API wrapped in delimiters (```)

This could really speed up my workflow and increase the usability of the extension.
