Grasshopper for Mac - Delete

Is there a way to change the settings so the Delete key deletes components not the backspace key?

Hi Tom-

delete deletes components for me. I just tested it on the latest RhinoWIP (5E334w).

What is your hardware setup? Laptop? Desktop?

Hi dan,

I’m using the same WIP.

It’s an iMac, I will post full specs tomorrow when I’m back in the office!


fwiw, delete key deletes components for me as well.
(ie- works as expected)

Hi Dan,

iMac (Retina 5K, 27-inch, Late 2015) 3.3 GHz Intel Core i5 16 GB 1867 MHz DDR3

If it helps in Rhino itself the “delete” does delete, so it is only in GH where only back space is deleting.

Could it be related to British Keyboards?

That’s what I’m wondering here. Thanks for the information that it does work in Rhino, but not Grasshopper…that’s an interesting clue.

Thanks. Just out of curiosity, does hitting fn+delete work to delete components on your keyboard?

Apologies for the delay,

I have tried fn + delete and it still does not delete!?

@will are you running macOS in en-GB with an Apple Keyboard purchased in the UK? Do you see this behavior in Grasshopper?

@dan I have the Magic Keyboard (without num pad), so no delete key.

Ah! The Magic Keyboard differs from British English…

to US English…

@tom.norris23 I’m still not sure this is the keyboard. That said, what does your keyboard look like?

Hi Dan,

The keyboard I was using was like the top image you posted but it included a num pad, and delete keys above sperated arrows, the home and end key were arrows and the return key was L shaped
I think is is the one circled in this photo:

Well, I’m stumped. I wish I could reproduce this on my end. I presume when you swap out keyboards, this problem persists (?)

Unfortunately I am no longer in a position where I can test this setup, sorry I cant be more help.
