Searchable Navbar is a Visual Studio extension that replaces the standard navigation bar with a searchable navigation bar. It uses Universal Ctags to generate the function tags, so any language supported by Universal Ctags is also supported by this extension.
How to set up
After installing the extension, an additional navigation bar will be available at the top part of the active document. You can assign a shortcut to open the navigation bar and start searching by going to Tools >> Options >> Environment >> Keyboard, the command name is SearchableNavbar.Open.
Optionally, you can disable the default Visual Studio navigation bar from Tools >> Options >> Text Editor >> (Language) >> Navigation Bar.
For more options right click the navigation bar or go to Tools >> Options >> Searchable Navbar.
