Mouse

    The mouse is used for two purposes. First you can change the viewport of the spectrum. To do so, you can set viewport-markers with mouse clicks. Second you can use it for cut and paste text as well as positioning the cursor in the text-window.

 

While the cursor is placed in the graphic-pane (cross-hair cursor), the left mouse button (#1) sets a marker and the other buttons perform certain actions each. The middle button (#2) expands the region between the marker and the border in which the cursor is positioned and the right button (#3) expands the region between the marker set with #1 and the current cursor position.

 

You may set a vertical marker (single click #1), a horizontal marker (double click #1) or a corner marker (triple click #1). A corner marker is a combination of a vertical and a horizontal marker and defines a corner of a rectangle. Leaving the tv-root window deletes all viewport-markers set.

With the cursor on the scales gumby-cursor the left mouse button shifts the displayed spectra to the left and the right button to the right.

 

In combination with the keys Strg Shift #1 shifts the viewport to the left, #2 centers the viewport at cursor position and #3 shifts the viewport to the right.

The configuration of the mouse buttons can be defined in your .Xresources file (see appendix B p. ) which will overwrite the default settings.

The x- and y-position of the cursor is displayed in the status bar of the window the cursor is in (see 3.1 p. ). If a calibration is loaded, the x-position is displayed both calibrated and uncalibrated (in parenthesis).
