vi edit mode improvement requested for long lines & long multi-line chats

Can you please introduce more basic vi commands into the terminal to ease editing long lines and long multi-line chats.

When in vi edit mode and editing a long line, k and j go to the beginning and end of the line and there doesn't seem to be an easy way to navigate within the line, for example / to search is not available, making it very cumbersome to edit long lines.

: is not available to go to a specific line number or 0 beginning of chat / $ end of chat, making editing long multi-line very cumbersome as well. This would also be useful for something like clearing a chat (:0,$d).
