make MacOSX applications with RS XE2 (step-by-step)

[LP]

There is just one 3-key shortcut you need on Lazarus: CTRL+SHIFT+C , which is code completion:

The 3-key combinations I find particularly annoying are Step into/Step over, Toggle form/unit view, View Object Inspector, View Units and View Forms. In Delphi/Lazarus on Windows the first three are 1-key, while the other two are 2-key. Debugging keys are essential and very common to use; I can't believe you have to hit 3 keys for every single line of code, same applies to Form/Unit view.

Most other useful combination are just two keys:
CMD + R : Run and debug application (Lazarus and Xcode)
CMD + U : Unindent code block
CMD + I : Indent code block

In Delphi they are F9, Tab and Shift+Tab respectively (Delphi versions previous to XE 2 need CnWizards for code block indentation). They are shorter and more intuitive.

I think after a while you get used to the shortcuts, at least that has always been my experience.
I don't think the Lazarus team will change the shortcuts on Mac OS, as most of them are the same on Xcode, which is I find rather pleasing, personally, as I've been doing a lot of Xcode development these days.
