| Edit menu basics
This describes the portion of the EDIT menu covering topics other than respirometry. See the Respirometry submenu for gas exchange calculations.
For BASELINE, INTEGRATE, DERIVATIVE, SMOOTHING, GAS EXCHANGE, and some other EDIT menu calculations, clicking the plot window is equivalent to clicking a highlighted button.
The small pop-up menu in the upper right corner of the plot area is one of several ways to select the 'active' channel from a list of available channels, which is updated whenever you alter the current channel labels (by loading a new file, editing a channel label, creating or removing a channel, etc.).
The effect of selecting a new active channel depends on whether you are in single- or multiple-channel display mode. In single-channel mode, the new active channel replaces the old one in the plot area, and the active channel indicator at the upper right of the plot area is updated. In multiple-channel mode, only the active channel indicator is changed.
Other methods for channel selection:
Use the number keys: Press the key that corresponds to the number of the channel you wish to use (press '1' for channel 1, etc.). Use the 0 (zero) key for channel 10. For channel numbers above 10 (to a maximum of 20), use a combination of the shift key and a number key (i.e., press shift 1 for channel 11, shift 2 for channel 12, etc.).
Use the up and down arrow keys: The 'up' arrow sets the active channel to the next higher channel number, and the 'down' arrow sets the active channel to the next lower channel number.
Note that this method will 'wrap' at channel 1 and at the highest-numbered channel. In other words, if the active channel is 1 and you press the 'down' arrow key, the active channel is set to the highest-numbered channel available. Similarly, if the active channel is equal to the highest-numbered channel and you press the 'up' arrow key, the active channel is set to 1.
In multiple-channel mode, use the buttons in the floating window: The pushbuttons on the floating 'toolbar' at right of the plot area indicate the channel in use (active channel) and let you select new active channels by button clicks. The other means of changing channels still work.
When performing a complex sequence of manipulations on data, remember that only one level of UNDO is available.
This means you can only reverse the most recent change, and for some operations that affect all channels, NO UNDO is possible.
