The recent version of Zed changed the caret movements of ⌥← and ⌥→ from one based on word boundaries to one based on sub-word boundaries, like when a case change occurs. If your caret was on the left of an identifier like MyFancyIdentifier, when you pressed ⌥→, instead of going to the end of the word, it’s moved to the front of “Fancy” since it detected a case change.
It’s a style of navigation I don’t care for. Fortunately you can turn it off by opening keymap.json and adding the following:
// keymap.json
[
{
"unbind": {
// -- Snip --
"alt-left": "editor::MoveToPreviousSubwordStart",
"alt-right": "editor::MoveToNextSubwordEnd",
"shift-alt-left": "editor::SelectToPreviousSubwordStart",
"shift-alt-right": "editor::SelectToNextSubwordEnd",
// -- Snip --
}
}
]
