This change updates the menu hotkey from e to 2, removes the old in game help hint about opening the menu with e, and updates the docs to reflect opening the menu with 2. It also adds the missing q: close hint to the menu box and updates the volume slider so it can be adjusted by dragging left or right instead of only clicking a position.

Why this change

• The new menu shortcut makes the menu easier for players to find and open, especially since it also contains the option to exit the game. Additionally, the previous quit shortcut on 2 was kind of redundant because quitting is already accessible via q, so reassigning 2 to open the menu makes better use of the key.

Summary

• Changed the menu open hotkey from e to 2.
• Removed the old help hint for opening the menu with e.
• Updated the docs to say the menu opens with 2.
• Added the missing q: close label on the menu box.
• Updated the volume slider to support dragging.
