Navbar Shortcuts for Desktop

[cartwatson]

Description

ctrl+shift+number to navigate between headers

• What problem would this feature solve?
  • Navigating multiple pages becomes easier and quicker
• Are there any potential downsides to this feature?
  • None that I can think of, if a user doesn't want to use them they don't have to and I chose ctrl+shift+number as that shouldn't clobber any system level shortcuts (these are used in the outlook webapp)
• If applicable, what would the configuration for this feature look like?
  • I don't see a need for this to be configurable but I could see how someone else might. If config was desired it would need to be a glance-level config option(s), but I think that it's more mess than it's worth from an implementation and user side.
  • Could add config to enable/disable the setup function
• Are there any existing examples of this feature in other software?
  • As previously mentioned this is used in the web version of Outlook to navigate between inbox, calendar, etc
• If applicable, include any external documentation required to implement this feature
  • Only needs a line to explain the shortcut, adding config would mean more docs

I'd like to implement this and have a rough draft in cartwatson/glance-fork
