<p><strong>Editing</strong></p>\r
-<p><em>Inserting / removing gaps</em> - hold down the "Shift" key. Click\r
- a residue with the mouse and drag the residue to the right to insert gaps or\r
- to the left to remove gaps.<br>\r
- If the residue selected is within a defined group, hold down either "Alt"\r
- or "Control" key and drag the residue left or right to edit all sequences\r
- in the defined group at once. </p>\r
+<p>There are two major ways to edit alignments - in 'Normal mode',\r
+gaps are inserted and deleted at the mouse pointer in various ways by\r
+clicking the left mouse button and pressing a combination of either\r
+shift and control (or the apple key on Macs) and dragging the mouse. Pressing\r
+<em>F2</em> toggles the alternative <a href="../features/cursorMode.html">'Cursor\r
+mode'</a> keyboard editing facility, where the space bar and delete \r
+keys add and remove gaps at the current editing position. The key\r
+strokes for both these modes are summarised in the <a\r
+href="../keys.html">keystrokes table</a>.</p>\r
+<p><strong>Tip:</strong> For large alignments, deselect "Calculate -> \r
+ Autocalculate Consensus" to prevent the alignment performing lengthy calculations \r
+ after every edit. </p>\r
+<p><em>Inserting / removing gaps</em> - hold down the\r
+ "Shift" key. Click on a residue with the mouse and drag it\r
+ to the left or right to insert gaps and remove gaps.<br>\r
+ If the current selection is a group over all sequences in the\r
+ alignment, or a group over some sequences or all columns in the\r
+ alignment, then hold down either "Control" \r
+ key and drag the residue left or right to edit all sequences in the defined \r
+ group at once.</p>\r
<p><em>Copy/paste/cut/delete</em> - any sequences which are in the current selection\r
box (indicated in red) may be cut and / or copied to a new alignment or deleted.\r
