Toolbars have a handle at the left hand side which can be clicked to minimize the toolbar. Toolbars that have been minimized have their handle appear just under the menu bar; click the handle to restore the toolbar to the last position it occupied. You can drag a toolbar's handle to move the toolbar to a different position in the toolbar area. Toolbars can be dragged out of the toolbar area entirely and made into stand-alone tool dock windows. To hide a tool dock window click its close button. To restore a hidden tool dock window, right click the tool area, then click the name of the tool dock window you wish to restore.</p><p align="center"><img align="middle" src="qd-filetoolbuttons3.png" width="208" height="46"></p><blockquote><p align="center"><em>File Toolbuttons</em></p></blockquote><h3><a name="2"></a>The File Toolbar Buttons</h3><ul><li><p><b>New</b><br> Click this toolbar button (or press <b>Ctrl+N</b>) to create a new project, form or file.
