The official guide is the Komodo docs as with any other software (EDIT: I assume they have their own docs though…). Unfortunately, no, there are non that i’m aware of that have been translated into Spanish.
There are also built in tutorials in Komodo: Help > Tutorials >
As for all the tricks that you can do in Komodo…use it and always ask us about features you want. It may already be there. If it isn’t we might add it. If we won’t add it, it could possibly be very easy for you to write as a macro (or already be a macro).
In Sublime Text select a word I press ATL + F3 and select all occurrence in the document but puts the cursor in each of them and do multiple editing. In Komodo to do this, select the words but only one of them is editable.
We don’t use that workflow. But that would be refactoring which we do have. Right click word > Refactoring > Rename Variable. This method should take scope into account in your file. I don’t think Sublime would do that as Code Intelligence is not native to Sublime.
