@*~RSC_HELP_ALIPANEL The central view of the Strap application is the alignment panel. The sequence labels can be dragged up or down in the row header to change their order. In the amino acid sequences, white space (i.e. alignment gaps) can be added or removed.

Multiple alignment windows: If two or more alignment views are displayed at the same time (HTMLDOC_ITEM:SBUT_NEW_PANEL!), they display the same alignment. But if two independent Strap sessions are run in parallel, both display different alignments. Sequences and residue selections can be exchange copied from one to the other by Drag-n-Drop.

Shading: Three residue shadings are available in the tool-bar: "charge", "hydropathy" and "chemical". Alternatively, secondary structure can be highlighted: Helices are painted red and sheets yellow. Further GUI controls are in the context-menu.

Editing: Manipulation of the multiple sequence alignment is performed with the keyboard. See help menu for details.

Cursor: The cursor position is shown as a flashing white rectangle in the alignment window. Usually only the alignment row containing the cursor is changed when for example a gap is introduced by pressing the space bar. If more than one sequence is selected, then gaps are introduced into all selected sequences.
Residue selections are highlighted in the multiple sequence alignment. When the mouse is over a highlighted residue a balloon message appears. Right-click opens the context menu and Ctrl+left-click selects the selection. It can also be selected by dragging a rectangular region.

Scrolling: The horizontal scroll-bar outlines the entire alignment and shows selections and plots. It can be enlarged with the mouse. If there are many sequences, the vertical scroll-bar is active. But also the horizontal scroll-bar can scroll vertically. Try turning the mouse wheel with and without Shift and Ctrl. See Shortcuts. *@
