UPARROW/DNARROW keys
The [UPARROW] or [DNARROW] keys do the following:
●
In a numeric edit dialog box, increase or decrease the instrument parameter.
●
In a list, scroll forward and backward through the list entries.
●
In a table, move the selection bar vertically.
●
In windows or dialog boxes with vertical scroll bar, move the scroll bar.
LEFTARROW/RIGHTARROW keys
The [LEFTARROW] or [RIGHTARROW] keys do the following:
●
In an alphanumeric edit dialog box, move the cursor.
●
In a list, scroll forward and backward through the list entries.
●
In a table, move the selection bar horizontally.
●
In windows or dialog boxes with horizontal scroll bar, move the scroll bar.
UNDO/REDO keys
●
The [UNDO] key reverts the previously performed action, i.e. the status before
the previous action is retrieved.
The undo function is useful, for example, if you are performing a zero span
measurement with several markers and a limit line defined and accidentally
click the "ACP" softkey. In this case, very many settings would be lost. How-
ever, if you press [UNDO] immediately afterwards, the previous status is
retrieved, i.e. the zero span measurement and all settings.
●
The [REDO] key repeats the previously reverted action, i.e. the most recently
performed action is repeated.
The [UNDO] function is not available after a [PRESET] or "RECALL" opera-
tion. When these functions are used, the history of previous actions is
deleted.

Softkeys
Softkeys are virtual keys provided by the software. Thus, more functions can be
provided than those that can be accessed directly via the function keys on the
device. Softkeys are dynamic, i.e. depending on the selected function key, a dif-
ferent list of softkeys is displayed on the right side of the screen
