Quick start
- Download the ZIP from Releases and extract the entire archive into a permanent folder.
- Run
KSwitcher.exe. Keep thedictionariesfolder beside the application. - Double-click the tray icon to open Settings.
- In Settings → Languages → Default language cycle, enable the layouts you need and arrange them using Move up / Move down.
- Adjust shortcuts as needed and click Save.
To correct text manually, select it and press Next layout. With Convert recently typed text when nothing is selected enabled, you can correct recently typed text without selecting it first. Switch Windows input layout after conversion also changes the layout for subsequent typing.
Features in screenshots
Examples use demonstration data. Changed Settings and auto-correction screenshots were removed for v0.6.28; use the current written steps and replacement examples.
1. Layout correction
Select ghbdsn and use Next layout to get привіт. Enable recent-text conversion to do the same without selecting it. The image is a demonstration window showing results from KSwitcher’s conversion functions, not an additional application dialog.
2. Layout switching
Enable languages in Layout cycle, arrange them with Move up / Move down, and assign Direct layout shortcut to jump straight to a language. Available layouts come from Windows.
3. Auto-correction
Type hj,bnm followed by Space to get робить when Ukrainian is enabled and the word is in its dictionary. Add correct spellings in My dictionary. Resize this dialog to give the three dictionary editors more space.
4. Text tools
Change case cycles hello world → Hello World → HELLO WORLD. Transliterate converts Київ → Kyiv; Undo restores a conversion. This demonstration shows actual conversion-function results.
5. Clipboard history
Open history with Win+V, search for an earlier item, and press Enter to paste it. Ctrl+P pins an item; Shift+Enter pastes plain text. Text, images and file lists are supported.
6. Previews
Select an item and choose Open item / Ctrl+O to read its full contents; the screenshot shows a multiline text entry. Image entries have thumbnails. HTML/RTF can preserve formatting when pasted; use plain-text paste when you do not want it.
7. OCR
Images are recognized locally in the background, so searching a word can find its source image. Use Windows OCR or enable an installed Tesseract 5 with models such as ukr+eng+rus. Check installation checks availability; OK → Save applies the choice.
8. Snippets
Use ;hello for a greeting, ;thanks for a signature, or ;check for a multiline checklist. {cursor} positions the caret inside the expanded text. Triggers work across keyboard layouts.
Example: ;run → rider .{enter} (insert text and press Enter).
9. Shortcuts
Click a shortcut field, press the desired combination, then Save. Backspace / Delete clears a field. Existing shortcuts survive updates; ordinary Windows combinations such as Win+V can be assigned.
10. Screenshots
Press Win+Shift+S, capture a region, and open the thumbnail notification to annotate it. Add arrows, numbers, highlights, text or shapes, then copy the result or save PNG with Ctrl+S. The editor initially selects Pencil (F); this example shows the Save button and demonstration annotations.
11. Startup
Enable Start with Windows. For elevated target applications, optionally enable Start with Windows as administrator and confirm Windows UAC. Saving this setting does not elevate an already running process.

Newest item on opening history — v0.6.44 (2026-11-05)
Opening clipboard history now selects the newest matching item and scrolls to it, instead of restoring an older selection. After a screenshot has been recorded, reopen history to select it. Search and ★ Pinned only remain saved: clear the search and uncheck the filter if the new screenshot is hidden. Background clipboard/OCR refreshes preserve your selected record while you browse. Pressing the history shortcut again while its window is already active retains the existing quick-paste behavior. No shortcut or setting was added; the existing control-layout screenshots remain applicable.

Mouse Without Borders and verified snippets — v0.6.43 (2026-11-04)
Update KSwitcher on both PCs, especially the computer sharing its physical keyboard. KSwitcher now lets downstream keyboard hooks route events before processing them and ignores consumed events on the source computer. Delivered remote input still supports shortcuts, recent typing, automatic correction and snippets. An older source-side instance can still start duplicate operations and publish temporary clipboard markers. Closing that instance is a temporary workaround until it is updated.

The former filter dropdown is now a ★ Pinned only checkbox: check it for pinned entries, uncheck it for all entries. One click toggles the filter. The checkbox sits on the left with a small gap before the search box; the search box stretches to the same right edge as the history list when resizing. Text search, immediate removal after Unpin and remembered filter state still work. Existing saved filter state is preserved. An empty list means no pinned entries match the search. Clear history… still deletes all entries after confirmation, including those hidden by search or the checkbox. No shortcut or default changed.

History opens in a separate, short-lived instance of KSwitcher.exe. Esc closes it even when focus is on the window or an action button, releasing Windows UI allocations with the process. The resident keeps keyboard hooks, clipboard capture and history storage. Search and the pinned-only filter are preserved in encrypted view state. From v0.6.44, each fresh opening selects and reveals the newest matching entry; background refreshes preserve the selected record while browsing. If a full-text item viewer is still open, the helper stays alive until the last viewer closes. Pin/delete, formatted/plain paste and OCR remain available; settings and default shortcuts are unchanged.

Previous release — v0.6.22 (2026-10-31)
From v0.6.22, recent-text conversion, repeat conversion and undo can recover a partial selection. If copying returns a verified suffix of the expected text, KSwitcher extends the selection with paced Shift+Left presses and copies again. It replaces text only after the complete expected range is verified. Recovery is attempted once; an empty or unrelated range is not extended, and a changed input context still cancels the operation.
Recent-text verification maps physical keys through convertible layouts, including Cyrillic and mixed case. Examples include Switcher from PuntoSwitcher , зштп from the layout equivalent of snipping , and лувШт from LinkedIn . Diagnostics now include the expected previous result and suffix-recovery stages. Shortcut assignments, layout-cycle settings and paste readback checks are unchanged.
Native regression tests cover suffix verification, and isolated-editor integration tests cover recovery of PuntoSwitcher and clipboard restoration. Direct validation in LinkedIn and ChatGPT is still outstanding. Editors may process simulated input differently; if full verification fails, conversion is cancelled. Include the copied diagnostic details when reporting another failure.

Previous release — v0.6.21 (2026-10-31)
From v0.6.21, Next layout skips enabled layouts whose conversion leaves the text unchanged, following the configured cycle until a changed result is found. Russian рф skips Ukrainian and becomes English ha; Ukrainian шььш skips Russian and becomes English immi when English follows in the configured cycle. Each candidate is calculated from the original text. Only enabled convertible layouts are considered.
If none changes the text (for example, 123 or shared letters with only Russian and Ukrainian enabled), the text stays unchanged and the operation advances one layout. The Windows input layout switches only when Switch Windows input layout after conversion is enabled. Direct layout shortcuts still target the chosen language. Default shortcuts and automatic correction are unchanged.
