Grimrock

hi @ all,

in order i build some levels years ago in dungeonmaster, i thought i understand the grimrock 2 editor, but there are few questions
(ive looked steingrimurs video tutorial):

#1 are there no "undo" button/function?
#2 are there no "copy all" [things from one square] button/function?
#3 are there a way, to read out basic informations (floor-/ceillevel) from a dungeon_floor, in order it works with items?
#4 does a "counter" anytime disable hisself when doing his job?
#5 i do not understand the "timer"

simple example: pressure plate open/closed a pit. works fine.

but if i want a delay to do this, i think i have to use the timer (i dont want to script such elemental easy things], same way i know from the dungeonmaster editor:
pressure plate activated ->timer,
timer = triggering on start, with 2sec delay, toggle the ->pit

but whats happened? the timer did his job without beeing triggered from the pressure plate...on/off,on/off

#4 are there a way, to read out basic informations (floor-/ceillevel) from a dungeon_floor, in order it works with items?
#5 does a "counter" anytime disable hisself when doing his job?

#2 = left mouse holding down =)
