If I’m using cell selection mode, and I’m at the same time is inside a cell, in cell edit mode (i.e. moving the cursor inside the cell, selecting parts of its contents) and then filter away that line (using a macro executed by a shortcut), EmEditor will then get into an inconsistent mode, where it’s seemingly still in cell edit mode (cell is surrounded by dark-green border, and cursor is shown), but the cursor can be moved outside of the selected cell (e.g. into the cell to the left of that cell).
