If you really want to speed up this process without using the object editor, learn

(You need to have some programming experience)
If you want to do this you'll need to make a loop that iterates through a range of raw codes.
Then you can alter all the objects within the range of raw codes like this:
JASS:
//! externalblock extension=lua ObjectMerger $FILENAME$
//! i local rawcodes = {}
//! i rawcodes[1] = "A000"
//! i rawcodes[2] = "A001"
//! i rawcodes[3] = "A002"
//! i for i=1, 3 do
//! i modifyobject(rawcodes[i])
//! i makechange(current, "ahky", "Q")
//! i end
//! endexternalblock
In this example all abilities with raw code A000 - A002 will have their hotkey set to Q.
You might want to use a better way of targeting the raw codes so that you won't have to manually type them in one by one.
You'll need to find a pattern.
An example of how to use such a pattern:
JASS:
//! externalblock extension=lua ObjectMerger $FILENAME$
//! i local rawcodes = {}
//! i for i=0, 9 do
//! i rawcodes[i] = "A00" .. i
//! i modifyobject(rawcodes[i])
//! i makechange(current, "ahky", "Q")
//! i end
//! endexternalblock
This will set the hotkey to Q for all raw codes from A000 - A009
Of course if you understand how this works, more customized patterns can be made
(A very advanced customized pattern that searches for specific jumbled up abilities probably takes more time then adjusting it in the object editor though xD)
If all of the abilities that need Q as their hotkey have something in common, it's simple. If not, it would probably be better to edit them inside the object editor.
Same goes for the other hotkeyed abilities.
You might need some advanced knowledge in order to use Lua Object Generation.
