Hello!
The delete key on the mac used to delete the previous character to the left. But now it deletes the next character to the right. I'm on a macbook pro with 10.14.6
This could be seen as just an annoyance as one can actually learn how to deal with the new behaviour I guess... though some habits die hard for old monkeys like me (I still use command + shift + H when I want a horizontal slider, but end up loudly cursing at myself when I hide Pd's window). But the problem is that this is not how the delete key works on macs for every other software, so it's very very conflicting and I do consider this a bug indeed. Moreover, this change was propably completely unintended. And I also got really thrown off by this until I figured out what was going on - it just did feel like a weird and uncontrollable bug. Even after having figuring it out, I just keep screwing things over and over.
This seems to have something to do with the changes to the keyboard settings from Pd 0.50-1 that fixes issues in PCs for portuguese/spanish keyboards. Since this change doesn't macs, I'm just sticking to Pd 0.50-0 for the moment.
Anyway, not sure how hard would it be to go back to the earlier and correct behaviour, I hope it's not too much of a headache and that we could have this sorted on a Pd 0.50-2 release soon to come.
Thanks
