How can I move my cursor to the next (or previous) whitespace char?

Question

Let's say I have a block of text like My website iss https://www.example.com/123/456█, where █ represents where my cursor is.

In vim, I could just hit B (as opposed to b) to go back a WORD (as opposed to a word), getting me to My website iss █https://www.example.com/123/456 in one movement - where I can easily fix the typo in is.

But in regular mac text boxes, there's no easy way to do this. I can move to the previous word with Option + Left Arrow. Doing this 6 times works:

• https://www.example.com/123/456█
• https://www.example.com/123/█456
• https://www.example.com/█123/456
• https://www.example.█com/123/456
• https://www.█example.com/123/456
• https://█www.example.com/123/456
• █https://www.example.com/123/456

Or I can move the cursor to the beginning of the current line with Command + Left Arrow. (And then move back to the right if I overshot). But neither are as good as being able to do what I want to do. Consider / and . as part of the "word" movement when doing option + arrow.

Any recommendations?
