/multiline ; /doaction1; /doaction2; /doaction3
Now, this would do 3 actions, or commands,but they would activate basically at the same time, like no delays or pauses between them, thisusually causes skills and other commands to fire when you dont need em just yet.
For Multiline command we dont have a proper pause we can put in, however we can send commands on timed countdown
Try this example in your mq2chatwindow to get an idea of how timers work in multiline
/multiline ; /timed 20 /echo i am number four!; /echo i went first!; /timed 10 /echo lulz! i gonna go third; /timed 5 /echo yes! i am second
Timed command starts a timer, and once that timer is counted down it fires the associated command
/timed 10 /echo hi friend
Unfortunately this can be a bit tricksy to get to work proper with some skills and commands, but usually once you get it nice and right, it works pretty well
