It’s kind of modal editing. Your 99% is enter to send because it’s a chat program. You’re sending mostly quick messages where adding a chorded input to send is just adding extra work to that mode.

When you enter a code block, that assumption changes. You are now in a “long text” mode where the assumptions are shifted where you are more likely want to insert a new line than to send the message.

I think people that have used tables or a spreadsheet and a text editor kind of understand modal editing and why we shift behaviors depending on the context. Pressing tab in a table or spreadsheet will navigate cells instead of inserting a tab character. Pressing arrow keys may navigate cells instead of characters in the cell. Pressing enter will navigate to the cell below, not the first column of the next row. It’s optimized for its primary use case.

I think if the mode change was more explicit it’d maybe be a better experience. Right now it is largely guessing what behavior someone wants based off the context of their message but if that mismatches the users expectations it’s always going to feel clumsy. A toggle or indicator with a keyboard shortcut. Can stick the advanced options inside the settings somewhere if a power user wants to tinker.

The worst part is if I paste markdown it's not formatted automatically.

This is a user preferences setting for what it's worth.
