Bug: Console navigation differs from all other Source games

[jason-e]

Describe the bug

CSGO, CSS, TF2, Portal 2 and probably all Source games have exactly the same console autocomplete/history keyboard navigation behavior, but the Chaos Panorama console currently has different behavior. It was previously thought that CSGO actually had divergent behavior and that this behavior is what Chaos uses, but that is not the case.

Chaos's console navigation should exactly match other Source games because that is what players are used to, with many years of muscle memory. Classic Source console navigation is also very effective with some underappreciated attention to detail, so there's really no reason to diverge from it.

How the console behaves in other Source games, and which behaviors Chaos currently matches

Autocomplete

• [x] Type some characters -> autocomplete shows up
• [x] Press tab or down arrow to cycle forward through suggestions, shift+tab or up arrow to cycle backward.
• [x] When navigating to a new autocomplete suggestion, the entry box is updated with that suggestion plus a trailing space. (on Chaos, you must navigate with the arrow keys and then commit to the selection with tab to actually update the entry box)
• [ ] Typing anything after filling in an autocomplete suggestion locks in that text, updating the autocomplete suggestion list in the process. Moving the cursor left or right with the arrow keys does not lock in the suggestion yet.
• [ ] Typing something followed by a space stops the autocomplete suggestions, but deleting the space restores suggestions (e.g. type "cl_allow" to see suggestions, add a space to stop the suggestions, delete the space to restore the suggestion box).
• [x] Pressing enter submits the entry as-is, even if it is filled in with a suggestion that hasn't been "locked in".

  History

• [x] With an empty entry box, tab/shift+tab/up/down cycle through input history in the same way they would cycle through autocomplete suggestions (only up/down works on Chaos, though that's probably what most people use anyway)
• [x] When cycling through history, any inputs (both ConVars and commands) which had no arguments have a space appended automatically. Anything which had arguments has trailing whitespace removed automatically.

Panoramas console in and of itself is a panorama panel, it doesn't use the VGUI console logic, all the stuff that makes sources console the console has to be recreated, thank you for this panel, as it's helpful identifying what's required.

Should also make these hotkeys remappable, and default backwards navigation to ctrl-tab or the like since shift-tab is the default Steam overlay hotkey (although I'd still prefer shift-tab for UI navigation since I have a different overlay hotkey).

The VGUI console can also be closed by pressing the toggleconsole key which doesn't happen in the panorama one, that should probably be tied to a cvar like con_close_on_toggleconsole so you can turn it off if you actually want to type the ` character.
