Right, I played with these settings & I think the guilty one is smart tabs (still don't get how it works).
(Cannot find anything related to ndent in Codetools/General.)

Yes! The style class I was looking for is "text block". Now, I get a different bg color for the relevant parts and none for the rest of lines.

All right, but what about this feature [geany fans constantly use it and can hardly leave without ;-)]

Right, did it already in fact. Just miss the feature to which assign ctrl+D (duplication!).

Thank you! By me it's called "scroll past end of line", maybe the reason why I overlooked it... There is also "cursor beyond end of line" in Codetools/General: I unchecked it before but it does not seems to have any action.

Right, I don't use this because I want blank lines in an indented block to be correctly indented as well. I need this feature not to apply to blank lines (meaning be smart enough not to remove *leading* spaces that just happen to be also *trailing*)... there is an option for this in a few editors.

Thank you for all these tips,
Denis
