# Editing Values

Edit values by clicking into the cell, entering a new value, then pressing Return. The background of edited cells changes to indicate that they differ from the original value of the PV.

Note that changes are not written out to PVs, yet, until the changes are saved.

Cells in columns which have a gray background and a Tooltip that indicates read-only can not be edited. See Configuration Files.

## Change Multiple Limits To The Same Value

To set multiple cells in a row to the same value, select the desired rows, then right-click on one cell in the desired column and invoke Set Value from the context menu.

In the example below, the rows for "MEBT 1" to "CCL 4" were selected, then the right button context menu was invoked on one of the selected cells in the "PwrLmtAdm" column. After entering a value and pressing OK, the "PwrLmtAdm" cells for rows "MEBT 1" to "CCL 4" will be set to the entered value.

## Change All Limits In A Column To The Same Value

To set all the cells in a column to the same value, left-click the mouse on the desired column header.

Below, the "PwrLmtAdm" column was selected. This will obviously only be possible for editable columns, not for read-only columns, indicated by a grey background.

Pressing the OK results in the screen below. Note how all but the "RFQ" entry which was already set to a value of 1000 are highlighted to indicate the changed value, and the asterisk next to the window title (*rf_admin.pace) also reflects that some values have been changed.

## Revert Changes

To set selected edited cells back to their original value, select the desired rows, then right-click on one cell in the desired column and invoke Restore Original Value from the context menu.
