By any chance / any chance.
The `#` defines that the "by" does not have to be "by", but can be "any chance" / "a chance", or "just a chance".

Doing this should hopefully make typing easier, and hurt your hands less.
"Will you be able to play later #ac?"
- Will you be able to play later by any chance?

"#ac that I'll be off tomorrow"
- A chance that I'll be off tomorrow.

"There isn't #ac he'll win that fight."
- There is no chance he will win that fight. (There isn't a chance he will win that fight.)

It can also be used in other ways such as:

"Small #ac of that happening."
- Small chance of that happening. (Small a chance of that happening - the "a" is cancelled out by your common sense)

"#ac are low"
- Chances are low. (Again the sentence makes sense, the prefix is cancelled out.)
