ide - How to convert MATLAB code segment to single line? -

i'm looking way convert multi-line code such :

for i=1:10     foo(); end 

to :

for i=1:10, foo(); end 

is there easy way in matlab editor? preferrably reversable?

i think accidentally hit keyboard shortcut few days ago, , saw magic happen, couldn't find keys did press :)

thanks !

p.s. i'm not sure if question belongs superuser, believe can find quick answer here, , relevant programming, win-win !

it work if write way:

for i=1:10, foo();, end 

(note comma after foo();)

but did hit + or - before for, expand of collapse "for" code sequence.

if go in "view" tab, there buttons expand of collapse can use same.
