Feature request: Dynamic settings attribute(s) toggle

[mkitzan]

Description of the new feature/enhancement

Recently, a few issues have popped up expressing an interest in a feature which could support the dynamic switching of the colors and styling settings attributes of an open Profile. The following settings attributes could be made to support dynamic switching:

• colorScheme (if nothing else this is a must support)
• foreground
• background
• backgroundImage
• fontSize
• fontFace
• requestedTheme

Issues which are related to this generic feature request:

• Feature request: Presentation mode #4176, supporting switching to a presentation mode
• Theme-controlled color scheme switch #4066, supporting switching between light/dark colorScheme/theme
• allow dynamic switching of color theme per-tab (did we regress ColorTool?) #3687, supporting switching between colorSchemes (this one wants different colorScheme per tab, rather than all tabs of a certain profile)

Proposed technical implementation details (optional)

It would make sense to implement the switching trigger as a shortcut key binding which changes the present tab's colorScheme to a preset scheme. When the colorScheme has been switched and the shortcut key is pressed again it could return to the default scheme for the tab's profile.

Potentially this shortcut key could be bound to switch not only the colorScheme but also other settings attributes as well (like fontSize). The return to default behavior could be applied to all the switched attributes.

With a scope like this, it might be best to handle this as an extension. 😄 I've tagged it as such.

You know, the majority of this ask was probably accomplished by the setColorScheme action. I think we've got other requests laying around for setFontSize (instead of just adjustFontSize). Combine these sorts of things with a multipleActions action, and we might get the effect we're looking for here.
