-		<p>The white dots represent the clip points. The clip tool needs at least one clip point to create a clip plane. You can place clip points by clicking with the <b>left mouse button</b>, but you can only place clip points on the faces of the currently selected brushes. However, you can drag clip points off the faces (see below). You can delete the most recently placed clip point by hitting the <script>print_key("Delete");</script>. Once you have placed a point, the clip tool will try to guess a clip plane for you. If you need more control over the clip plane, you need to add more clip points as shown in the screenshots. Now the clip plane will be represented by a white line or triangle that has the clip points as vertices (see second and third screenshot).</p>
-		<p>The clip tool always gives you an instant preview of how the clipped brushes will look. Once you are satisfied with the clip plane, you can hit <script>print_key("Return");</script> to perform the clip. You can toggle between the three modes of the clip tool using the <script>print_key("Tab");</script> key. If you would like to cancel the clip operation, simply deactivate the clip tool.</p>

You can toggle between the three modes of the clip tool using the <script>print_key("Return", "CmdCtrl");</script> command. If you use the split mode (where both sides of the clip plane are kept) on a brush entity, the resulting brushes will be added to the entity. TrenchBroom will also remember the last clip mode you used and the resulting brush(es) selected, which can help make further clip operations quicker. If you would like to cancel the clip operation, simply deactivate the clip tool with <script>print_menu_command("edit_clip_tool");</script> or click in the void to deselect your current selection.</p>
