Using F3+Q, the game displays in chat the combinations of keys you can do using F3 and a letter. But a few words appear without spaces between them, while they should be spaced:

• keybindings
• resourcepacks
• renderdistance

Since the chat messages are simple strings, there's no technical reason to avoid the spaces in these words. So, in order to keep consistency, they should appear as they are displayed in the other places in the game.

Steps to Reproduce:
1- Press F3+Q.
2- Look at the help in the chat.
3- Go to somewhere where the same words are shown and compare with the chat list. They don't have consistent separation.

Also, for better grammar, the description "Shift to inverse" can be changed to "Shift to invert".
