hello every one.
i have three different questions and appreciate your help.
1- is it possible to install libreoffice x86 on 64 bit windows?
2- whats restart manager which is available in libreoffice 5.3.0?
what happen if i install libreoffice 5.2 and earlier on newer versions
of windows?
i use xp and not have any problem.
but i wish that know about installation of libreoffice 5.2. and
earlier on windows vista and newer.
3- i wish that change goto page shortcut key on libreoffice 5.1 and
5.2 from control+shift+f5 to control+g which is available in 5.3.
i tried customize keyboard, but i only could delete it not modify it!
is this feature (customize) accessible for blind users?
i appreciate your help and i pray divine mercy and blessings for you.
