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 mea-
surement with several markers and a limit line defined and accidentally click the
"ACP" softkey. In this case, very many settings would be lost. However, 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 per-
formed action is repeated.
The [UNDO] function is not available after a [PRESET] or "RECALL" operation. 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 provi-
ded than those that can be accessed directly via the function keys on the device. Soft-
keys are dynamic, i.e. depending on the selected function key, a different list of soft-
keys is displayed on the right side of the screen
A list of softkeys for a certain function key is also called a menu. Each softkey can
either represent a specific function, or a submenu that in turn represents several soft-
keys.
Selecting softkeys
► A particular softkey is selected by pressing the key on the screen with a finger,
mouse pointer or other pointing device.
Softkeys can only be operated via the screen, there are (usually) no corresponding
function keys.
Navigating in softkey menus
The "More" softkey indicates that the menu contains more softkeys than can be
displayed at once on the screen. When pressed, it displays the next set of soft-
keys.
