Greptile Summary

This PR fixes filtering mode in MultiSelect so that pressing Enter immediately confirms the current selection rather than merely saving the filter text and returning to normal mode. It achieves this by extracting the existing inline validation logic into a reusable try_confirm() method and calling it from both the filtering-mode and normal-mode Key::Enter arms, and updates the help hint from "save filter" to "confirm".

• try_confirm() collects the currently-selected labels, validates them against self.min/self.max, sets self.err on failure, and returns None — consistent with the pre-existing non-filtering Enter behaviour.
• The filtering-mode Key::Enter arm now calls try_confirm() and, on success, runs the same cleanup + render + return path that normal mode uses; the non-filtering arm is identically refactored to remove the old inlined validation.

Confidence Score: 5/5

The change is safe to merge; it correctly unifies two code paths around a shared helper and the guard that previously silenced Enter in filtering mode has been removed.

The extraction of try_confirm() is accurate and both call sites produce identical behaviour. No logic was lost and the help-hint mismatch noted in earlier review rounds is addressed in this diff.

No files require special attention.

Important Files Changed

Filename	Overview
src/multiselect.rs	Extracts try_confirm() helper and wires it into the filtering-mode Enter key, so pressing Enter while filtering now confirms the whole selection instead of just saving the filter text; help hint updated from "save filter" to "confirm".

Code Review

This pull request refactors the MultiSelect component by extracting selection validation into a new try_confirm method, reducing duplication in the Key::Enter handling for both filtering and non-filtering states. The reviewer suggests further deduplication by moving terminal cleanup and rendering logic into a dedicated confirm helper method. Additionally, an unnecessary guard in the filtering branch was identified that could prevent users from confirming valid selections when no options match the current filter.
