��Rebound Home and End keys don't work on Macs except when used in conjunction with the Command key.
Fortunately the VM already has code to handle rebound keys and is just missing entries for moveToBeginningOfLine and moveToEndOfLine, which the Home/End keys are commonly rebound to.
I've added those entries with this pull request:��https://github.com/pharo-project/pharo-vm/pull/49
