Describe the bug / provide steps to reproduce it

• mkdir -p a/b/c/d/e
• zed a
• Set "use_system_path_prompts": false
• Create a new file
• Save the file
• Initial state

• Input ./b

• Move the cursor ./b/c/d/e/ and press TAB.

• Input f.txt and press Enter.

Nothing happens and the file is not saved.

If TAB is not used and type the whole path manually, everything is just fine.

I can reproduce:
Add "use_system_path_prompts": false, to your setting.json

mkdir -p /tmp/issue21046/a/b/c
zed /tmp/issue21046/

cmd-n
cmd-s
./a, down, down, tab, bar.txt

Workaround: press enter instead of tab.
Thanks for reporting.

I believe this is the issue: tab is bound to picker::ConfirmCompletion while enter is bound to menu::Confirm:

zed/assets/keymaps/default-macos.json

Lines 651 to 658 in 489900e

	{
	"context": "Picker > Editor",
	"bindings": {
	"tab": "picker::ConfirmCompletion",
	"alt-enter": ["picker::ConfirmInput", { "secondary": false }],
	"cmd-alt-enter": ["picker::ConfirmInput", { "secondary": true }]
	}
	},

zed/assets/keymaps/default-macos.json

Line 19 in 489900e

"enter": "menu::Confirm",

The latter works, the former does not. I'm not sure why these are distinct actions, but as a temporary workaround add the following to you keymap.json:

  {
    "context": "Picker > Editor",
    "bindings": {
      "tab": "menu::Confirm"
    }
  },
