peek definitions - definition for the symbol <any symbol>can not be located

Definitions in general. Maybe I am expecting something that does not exist, but based on IDE use from looong ago, it seems that one of the simple great benefits was to click on a word, function, operator or whatever and get a definition and description.  I can not seem to get that to work in visual studio / visualmicro. 

I have included a screen shot of looking for the term "long".  I have tried it with "int" , "float", "char" etc.  but get the same error. 

I do seem to get some kind of a response if I try it on variables, but not what I expect.  

 Am I expecting something that does not exist?    I have spent a few hours searching and configuring and reading and watching youtube and have found many supposed solutions and have done a reinstallation.  I have tried to find the menu item 'vMicro>Toggle Hidden Files' but can not even find that setting, and don't know if it relates anyway. 

I have a few other "issues" but am working on them, but I don't want to spend any more time with this, if I am trying to get something to work that does not even exist.  Thanks for any help and also thanks for a very very nice add-on to VS.  see attached

Thanks for the report.

The hints supplied in intellisense in Visual Micro depend on what comments have been added to the toolchain files in use, and there is often very little information within the Arduino toolchains for keywords like long.

The hints are displayed when the variable is hovered over (or highlighted in the suggestions list), and comments can be added to show for your own code, example below:
Code
Select All
/*
@brief this is a variable
*/
long myVar = 0;

// My Int variable
int myIntVar = 0;


The Toggle Hidden files can improve intellisense in some cases, and can be found on "vMicro > Show/Hide Hidden Files", however in this specific instance I doubt there will be further information for the keyword "long" for example.  The Arduino website is often the best resource for these keywords:

Thanks for the quick reply.  While I don't fully understand what you are talking about, at least now I know not to beat my brains out trying to get it to work.  I guess my assumption was that these "tool chains" libraries or whatever they are would exist as C++ tool chains. (help data)  In any case, this helps so that I don't waste more time looking for something I will not find. 

It is a LOT to take in.   thanks for your help
