Keyboard and mouse functions

The

mouse can be used to carry out the normal program operating

functions such as the selection of menu items and fields. It can addi-

tionally be used for magnifying a section of a chromatogram (

zoom-

ing). To zoom a portion of the plot it is necessary to place the mouse

cursor to the upper left corner of the square to zoom, press the left

mouse button and drag the cursor to the lower right corner of the rec-

tangle. After releasing of the left mouse button the selected region will

be zoomed full-screen. If the cursor is active in the peak editor mode

then it can be moved by pressing down the right-hand mouse key.
The

keyboard can also be used to scale a chromatogram in the win-

dow, as described below.
