Is there any shortcut for CodeBlocks to format the code?
I haven't find any tip in google.
I found only "format use AStyle", but it come up with right mouse button only...
probably not by default but you should be able to assign it there:
Settings -> Editor -> Keyboard shortcuts -> Plugins -> Source code formatter (AStyle)
My favourite = Ctrl + A then Ctrl + Shift + F.
You (these are the default settings I believe) can select a block of code and press the Tab key. This will indent the entire block.
So for indenting a whole file: Ctrl + A, then Tab.
In addition, you can use Shift + Tab on a selected block to "unindent"
You can move through the open tabs with Ctrl + Shift + Tab.
As for the best shortcuts:
I like Ctrl + D to duplicate a line and
Ctrl + L to copy it.
Anyway, you can set whatever shortkeys you like in the Editor menu (there you will also be able to find all shortkey currently set).
