GENtle/Sequence map

The sequence map is used by most GENtle modules. It shows sequences of DNA or amino acids, as well as primers, features, restriction sites and more. The basic behaviour, however, is always similar.

Clicks
A double click usuaqlly opens the editor for the sequence.

Context menu
The available functions in the context menu vary with the module the sequence map is used in, its state, and selection.

Keys
The whole sequence can be marked by Ctrl-A. The ../Find/ dialog can be invoked by Ctrl-F. Both functions can also be called upon through a menu.

In the DNA and PCR modules, the amino acid reading frame can be toggled by keys like this:
 * Ctrl-1 = reading frame 1
 * Ctrl-2 = reading frame 2
 * Ctrl-3 = reading frame 3
 * Ctrl-4 = reading frame 1, complementary strand
 * Ctrl-5 = reading frame 2, complementary strand
 * Ctrl-6 = reading frame 3, complementary strand
 * <tt>Ctrl-7</tt> = all reading frames, one-letter code
 * <tt>Ctrl-8</tt> = known reading frames only (from the features)
 * <tt>Ctrl-0</tt> = hide amino acids
 * <tt>Ctrl-W</tt> = three-letter code (not when displaying all reading frames)
 * <tt>Ctrl-Q</tt> = one-letter code

Edit mode
Display and edit mode can be toggled by <tt>F2</tt> or the toolbar. During editing, the sequence display is maximized, and the DNA map is hidden, improving ease of edit. Depending on the current module, only some keys are allowed (in the DNA module, "A", "C", "G", and "T") by default; any other key will trigger a request to allow all keys for that sequence, for that session. The cursor can be moved similar to that in a text editor. Insert and overwrite mode can be toggled, except for some modules like PCR or Sequencing, where overwrite mode is mandatory. In these modules, backspace and delete are diasbeled as well.

When editing a primer in PCR mode, the "<tt>.</tt>" key copies the base at the current position from the 3'&rarr;5' or 5'&rarr;3' sequence, respectively.

Horizontal mode
In some modules, the sequence display can be toggled to horizontal. This can enhance visibility. Printing, however, is always done in standard ("vertical") mode.
