I am using Visual Studio 2015 with Intel Fortran 2016. I would like to be able to search for specific strings within a specific subroutine or function. Is there a Ctrl+F type functionality which can allow me to do something like this? Thanks
Perhaps not the sort of work flow you are thinking of, but you can do find and find all "in selection". Select the text of the procedure, Ctrl-F, change "Current Document" to be "Selection", navigate through the results.
If outlining is enabled, selecting the opening line for a collapsed procedure selects the entire contents of the procedure.
