Why isn't everything available in the command pallete?

There are quite a few commands that aren't available in the command pallete, and I generally find it much easier searching for commands than either going through menus or remembering shortcut keys...

Here are a few I can't find
- Bookmarking
- Expanding Selections
- Toggle Comments
- Switch Project

Is there any reason they aren't in the command palette?
I'd like to know the answer to this as well. All commands should be available from some kind of menu with auto-complete, if only to help me find something when I can't remember the keypress.
