+# 222_54 fix: override tooltip to Toggle cell alignment in tabular context only
+
+## How to test
+Open a tabular table in Mogan. Place cursor inside a cell. Check the focus toolbar - the toggle button should now show the correct cell alignment icon (tm_cell_left or tm_cell_center) and tooltip "Toggle cell alignment" instead of the misleading "Toggle numbering".
+
+## 2026/03/12 fix: override alternate icons and names in tabular context
+### What
+Override `alternate-first-icon`, `alternate-second-icon`, `alternate-first-name` and `alternate-second-name` in `table-menu.scm` to show correct cell alignment icons and tooltip when inside a tabular context.
+
+### Why
+The button was using `tm_numbered.xpm` with tooltip "Toggle numbering" but it actually toggles cell alignment (tabular vs tabular*). This was misleading to users.
+
+### How
+Used `tm-define` with `(:require (table-markup-context? t))` to override the icon and name functions only inside tabular context in `table-menu.scm`.
