Ctrl+click or [F1], doesn't function, if uses does not list the unit.
It is useful that ctrl+click it opens the defining source (I didn't know this "trick") - but it is no use, to locating a unit.
I already mentioned, here again ... it will work if:
+ You're using Lazarus
+ The component is installed and available on the component tab
+ You drop the component to the form
+ only works on form's source code (not the pas file you manually created)
Yeah, it won't work on non-form pas file. But not a 'real' problem. I then will usually click the mainform (even if I write a new non-visual component, I usually will generate a test form for it) and drop the component so I can 'learn' which it belong to and the methods and the properties and much ...
Of course I can start a browser or using the CHM, but that's not so easier. FYI, CHM reader is not installed on Linux by default.
