In Resharper there is a well known keyboard shortcut to navigate to next
(Alt+Down) or previous
(Alt+Up) member in code.
In plain Visual Studio (at least in VS2017+) you are able to add these shortcuts easily. There are
Edit.PreviousMethod commands which used to be available only for Visual Basic editor. Nowadays, as C# and Visual Basic are widely aligned, they are fully functional in C# code as well:
I will probably go for
Ctrl+Down which are bound to Scroll-Up/Down by default.
Thank you for all your help! Finally it works
