tested under Win8.1 x64 with 220.127.116.11.alpha0+
Build ID: 6b096f273ac9d7bbe93d2cb083958b3a04866d73
TinderBox: Win-x86@42, Branch:master, Time: 2014-12-04_22:57:23
same issue with older LibO releases and with OOo 3.3.0 and AOO 4.1.0 too.
STEPS TO REPRODUCE
1- open a new Writer file
2- click on Tools/Customize
3- hit the Keyboard tab and do some changes in the shortcut keys (i.e. select F2 and click delete)
4- click OK
5- go back to step 3 and click the reset button (either the upper or the lower one)
reset should bring back the original Shortcut Keys setup.
the changes you did in the Shortcut Keys configuration are not reverted.
actually the reset works only before clicking OK (step 4) but once you clicked that, all the changes cannot be resetted at all.
Ubuntu 14.04 x64
LibreOffice 18.104.22.168 release
Seems like it's an enhancement request (or a trivial/minor bug?)
@Tommy: If you disagree with the enhancement setting, feel free to set it to what you think is appropriate (just do so objectively of course :) )
