Preview selected statement before sending to the console

Hi! I have been working on a REPL console for some time, and I'm able to send a statement to the console, given the position of the cursor.

In the previous case, it's highly likely that the user wants to send the whole statement, so I want something like this menu in SQL to pick which statement should be sent to the console. Unfortunately, I can't find the classes that are doing this.

While I'm on it, I can't seem to find a way to increase the font of my console (by default), and CTRL+mouse wheel isn't working, while it does in the rust console, or in the R console (but, I looked at the code for a while, without finding how they did that 🥲 ).

Thanks in advance!
