how globally map altgr pivotal alt key?

i wish altgr pivotal act accurately left alt.

usually, i kind things , nonetheless i'm open opposite solutions.

i attempted this:

lcontrol & ralt::alt

and autohotkey displayed blunder alt being famous action.

then i attempted following code:

lcontrol & ralt::
  send {alt down}
  keywait lctrl
  keywait ralt
  send {alt up}
return

which arrange works - i'm means altgr pivotal accessing hotkeys, nonetheless still behaves differently:

when i press redeem left alt, initial menu vigilant tide way receives focus.

pressing releasing altgr book does nothing.

any ideas? even illusory autohotkey? (remapping right ctrl shift left siblings square cake)

note: i attempted switching alt lalt formula finished difference.
