problem with the remove all empire pins function

hi there

been a long time sins player and i have a problem wich pestered me in the past as well but a reinstall always solved it

namely the default remove all empire pins function is set to ctrl+` wich u can accidentaly press if u use (who doesent) control groups such ctrl+1 ctrl+2 and so on

once pressed all the planets desapear from the left side of the game window and makes navigating your various planets a nightmare and i dont know a way to reverse this , in the past i just uninstalled the game and did a clean install , for what ever reason it doesnt work this time , maybe because i have the steam version now

if anyone has an idea on how to fix this i would be gratefull

ty

ps: sry for my less then perfect english , its not my native language
