+## Deel 1: Keyboard Navigation v1.1 (Mac-vriendelijk)
+
+### Doel
+Keyboard v1.1 bouwt voort op v1 en maakt navigatie sneller op Mac zonder de bestaande muisflow of backendcontracten te wijzigen.
+
+### Shortcut scope (v1.1)
+- `Tab`: wissel actief paneel (`left` <-> `right`)
+- `ArrowUp` / `ArrowDown`: verplaats current row
+- `Enter`: open directory op current row
+- `Space`: toggle selectie op current row
+- `Escape`: wis selectie in actief paneel
+- `Cmd + ArrowUp`: ga naar eerste rij
+- `Cmd + ArrowDown`: ga naar laatste rij
+- `Alt + ArrowUp`: grotere stap omhoog
+- `Alt + ArrowDown`: grotere stap omlaag
+
+### State impact
+Geen nieuw globaal model nodig; uitbreiding op bestaand model:
+- per paneel blijft:
+  - `currentPath`
+  - `visibleItems`
+  - `selectedItems`
+  - `currentRowIndex`
+- globaal blijft:
+  - `activePane`
+
+Aanvullende constante voor stapgrootte:
+- `PAGE_STEP` (voorstel: 10 rijen)
+
+### Navigatie- en scrollgedrag
+- `Cmd + ArrowUp`: `currentRowIndex = 0`
+- `Cmd + ArrowDown`: `currentRowIndex = visibleItems.length - 1`
+- `Alt + ArrowUp`: `currentRowIndex = max(0, currentRowIndex - PAGE_STEP)`
+- `Alt + ArrowDown`: `currentRowIndex = min(last, currentRowIndex + PAGE_STEP)`
+- na elke indexwijziging: `scrollIntoView({ block: "nearest" })`
+- bij leeg paneel: alle row-shortcuts zijn no-op
+
+### Focusregels
+Shortcuts alleen actief als focus niet in interactieve controls zit:
+- `input`, `textarea`, `select`, `button`, `checkbox`, `contenteditable`
+
+Extra voor Mac-combinaties:
+- alleen onderscheppen als de combinatie exact matcht met ondersteunde shortcuts
+- geen brede override van browser/system shortcuts buiten scope
+
+### Regressierisico
+- Mac key-detectie kan verschillen (`metaKey`/`altKey` + `Arrow*` combinaties)
+- Overcapturing van `Alt+Arrow` kan botsen met OS/browsergedrag op sommige layouts
+- Onbedoelde interactie met bestaande klikselectie bij snelle keyboard/muis mix
+
+Mitigatie:
+- centrale keyboard dispatcher met expliciete guard
+- alleen exacte combinaties afvangen
+- bestaande click handlers ongewijzigd laten
+
+### Teststrategie
+Geautomatiseerd (beperkt):
+- bestaande UI smoke tests behouden
+- optioneel kleine statische regressiecheck op paneelstructuur ongewijzigd
+
+Handmatig (primair):
+- `Cmd+ArrowUp/Down` springt naar begin/eind van lijst
+- `Alt+ArrowUp/Down` springt met grote stap en scrollt correct mee
+- shortcuts werken alleen in actief paneel
+- shortcuts doen niets in inputs/checkboxfocus
+- bestaande v1 shortcuts blijven correct werken
+
+---
+
+## Deel 2: Wildcard selectie ontwerp
+
+### Doel
+Snelle bulkselectie op patroon in het actieve paneel, zonder backendaanpassing.
+
+### Trigger shortcuts
+- `Shift + +` (oftewel `Shift` + `=` op veel toetsenborden): selecteer items op patroon
+- `Shift + -` : deselecteer items op patroon
+
+### Scopekeuzes (v1)
+- Werkt **alleen op actief paneel**
+- Werkt **alleen op zichtbare items** (`visibleItems`), niet recursief
+- Werkt op **files én directories** in v1 (consistent met zichtbare lijst)
+- `..` parent-entry doet niet mee
+
+### Patroonformaat
+- Glob-achtig, minimaal:
+  - `*` = willekeurige reeks
+  - `?` = één karakter
+- Voorbeelden:
+  - `*.mkv`
+  - `S??E??*`
+  - `Project*`
+
+### Case sensitivity
+- Voorstel v1: **case-insensitive matching**
+- Reden: voorspelbaarder voor eindgebruikers en sluit aan op typische file-manager verwachtingen
+
+### Gedrag met bestaande selectie
+- `Shift + +`:
+  - additief: matchende items worden toegevoegd aan bestaande selectie
+  - niet-matchende selectie blijft behouden
+- `Shift + -`:
+  - subtractief: alleen matchende items worden uit selectie verwijderd
+
+### Minimale popup UX
+Eenvoudige modal/prompt met:
+- titel: `Select by pattern` of `Deselect by pattern`
+- één inputveld: patroon
+- knoppen: `Apply`, `Cancel`
+- compacte feedbackregel na apply:
+  - `N items matched, M changed`
+
+Paneelcontext:
+- popup wordt gestart vanuit actief paneel en toont dat expliciet (`Active pane: left/right`)
+
+### Wat expliciet nog niet in scope is
+- Geen regex-modus
+- Geen include/exclude in één dialoog
+- Geen persistente pattern-history
+- Geen backend batch-endpoints
+- Geen recursieve mapmatching
+- Geen geavanceerde filters op size/date/type
+
+### Regressierisico
+- Shortcut-conflict met keyboard-layouts (`+` op verschillende toetsen)
+- Matchlogica kan onduidelijk zijn bij verborgen bestanden (afhankelijk van `show_hidden`)
+- Onbedoelde selectie van directories als gebruiker file-only verwacht
+
+Mitigatie:
+- in popup korte hinttekst over scope (`visible items in active pane`)
+- heldere result-feedback (`matched/changed`)
+- parent-entry expliciet uitsluiten
+
+### Teststrategie
+Geautomatiseerd:
+- basis smoke: UI laadt, paneelstructuur blijft intact
+- (indien kleine JS-tests bestaan) unitniveau voor glob-matcher helper
+
+Handmatig:
+- `Shift + +` selecteert matchende zichtbare items in actief paneel
+- `Shift + -` deselecteert matchende geselecteerde items
+- inactief paneel blijft onaangeraakt
+- behavior met gemixte selectie (file+dir) is consistent
+- case-insensitive matching bevestigd
