Hello, Anon Craigs
Yes, indeed, there are shortcuts for the behaviour that you would like to :-))
The DEFAULT main rules about Folding/Unfolding are :
A) The classical menu options, in the View tab, or the SHORTCUTS actions :
Fold All Levels ( ALT + 0 )
Unfold All Levels ( ALT + SHIFT + 0 )
Fold CURRENT Level, keeping the state of its sub-levels UNCHANGED ( Folded / Unfolded ) ( ALT + CTRL + F )
Unfold CURRENT Level, keeping the state of its sub-levels UNCHANGED ( Folded / Unfolded ) ( ALT + CTRL + SHIFT + F )
Collapse Level N, keeping the state of ALL the sub-levels UNCHANGED ( Folded / Unfolded ) ( ALT + Key N )
Uncollapse Level N, keeping the state of ALL the sub-levels UNCHANGED ( Folded / Unfolded ) ( ALT + SHIFT + Key N )
B) The MOUSE gestures :
Single LEFT click, on a [-] symbol, fold the CURRENT level, keeping the state of ALL the sub-levels of the CURRENT level
( Folded / Unfolded )
CTRL + single LEFT click, on a [-] symbol, fold the CURRENT level, as well as ALL the sub-levels of the CURRENT level, till the INNEST level
Single LEFT click, on a [+] symbol, unfold the CURRENT level, keeping the state of ALL the sub-levels of the CURRENT level
( Folded / Unfolded )
CTRL + single LEFT click, on a [+] symbol, unfold the CURRENT level, as well as ALL the sub-levels of the CURRENT level, till the INNEST level
Note : For this last action, you may, also, use the mouse gesture : SHIFT + single LEFT click, on the [+] symbol
