-# [202_105] "Meta" will appear in the keyboard shortcut notification pop-up
 
-### How to test
-1. Open Mogan on Linux
-2. Open a new empty document
-3. Press `Tab` key
-4. Verify the notification shows "Use Super+Tab in order to insert a tab" (not "Meta+Tab")
+# [202_105] Search and replace: add "Replace all occurrences" button
+
+## How to test
+1. Open a document with multiple occurrences of a word (e.g. "hello" appearing 5 times)
+2. Open search and replace (Edit → Search and replace)
+3. Place cursor in the middle of the document (e.g. after the 3rd occurrence)
+4. Enter the search term "hello" and the replacement "world"
+5. Click "Replace all further occurrences" (or press Ctrl+Enter / Command+Enter)
+6. Confirm that only the occurrences **after the cursor** are replaced (original behavior preserved)
+7. Undo, then click "Replace all occurrences"
+8. Confirm that **all 5 occurrences** are replaced, including those before the cursor
 
 ## 2026/02/25
 ### What
-Replace "Meta" with platform-appropriate key name in keyboard shortcut notification pop-ups:
-- Linux: display "Super" instead of "Meta"
-- Windows: display "Win" instead of "Meta"
-- macOS: display "Command" instead of "Meta"
+Add a separate "Replace all occurrences" button that replaces every match in the entire document, while keeping the original "Replace all further occurrences" button and behavior.
 
 ### Why
-On Linux/Windows, the `M-` modifier key is displayed as "Meta" in notification messages like "Use Meta+Tab in order to insert a tab". Modern keyboards do not have a key labeled "Meta" — on Linux the key is labeled "Super" and on Windows it is labeled "Win". This confuses users who cannot identify which key to press.
-
-Fixes: https://github.com/XmacsLabs/mogan/issues/2822
+Users expect a way to replace every occurrence in the document regardless of cursor position (issue #2857). The maintainer requested this as a separate button so the original "Replace all further occurrences" behavior is preserved.
 
 ### How
-In `system_kbd_initialize` in `src/Texmacs/Server/tm_config.cpp`, changed the Qt branch mapping for `"M-"` from a single `localize("Meta::keyboard", true)` to platform-conditional:
-
-```cpp
-if (os_win ())
-  h ("M-") = localize ("Win::keyboard", true);
-else if (os_macos ())
-  h ("M-") = localize ("Command::keyboard", true);
-else
-  h ("M-") = localize ("Super::keyboard", true);
+Added a new `replace-all-occurrences` function that calls `(search-extreme-match #f)` before the replace loop to navigate to the first match, so replacement starts from the beginning of the document. The original `replace-all` function is kept unchanged.
+
+```scheme
+(tm-define (replace-all-occurrences . args)
+  (let ((u    (if (null? args) (master-buffer)  (car args)))
+        (raux (if (null? args) (replace-buffer) (cadr args))))
+    (and-with by (or (by-tree raux) current-replace)
+      (with-buffer u
+        (search-extreme-match #f)  ;; Go to the first match
+        (start-editing)
+        (while (replace-next by)
+          (perform-search*))
+        (end-editing))
+      (perform-search*)
+      (set! isreplace? #t))))
 ```
 
-Also removed the now-unused `("meta::keyboard" "")` entry from `TeXmacs/plugins/lang/dic/en_US/zh_CN.scm`.
