8. Editing

Start input: double-click, a second click on the selected cell, F2, Enter, or straight away a digit, +, -, . or , (the old value is replaced).

Several cells at once: select an area and start input with Enter or straight away with a digit — the saved value is written into every selected cell as one entry in the undo history. In smoothing mode only the current cell is edited.

Input is in the map's real units, as in the table. The fractional part is entered with a point or a comma.

The input field's tooltip shows the allowed step from the catalog. An invalid number is highlighted with a red frame, and a message is shown in the status bar. A saved value goes into the undo history.

A double-click on an axis header, F2, Enter or straight away a digit opens input; Enter saves, Esc cancels. Axis values must increase — otherwise a warning in the status bar. Changes go into the undo history.

Bulk operations on an axis (the "Map Editing" toolbar, the "Axis:" group, with an axis selected): +% (by percent), + (add), × (multiply).

Shared axis. In a firmware, one axis is often shared by several maps. Before writing such an axis, the program shows the "Shared axis" dialog: "Row axis/Column axis of this map is stored in the same firmware bytes as the axis of the following maps (N): … Writing will change the axis breakpoints in every one of them. Continue?". No is selected by default; declining writes nothing ("Axis breakpoint write cancelled"). A long list is truncated: "… and N more".

If the axis is defined by the catalog or computed, it cannot be edited: "The axis of this map is not editable: its breakpoints are defined by the catalog or computed, and the firmware holds no data for them".

On the "Map Editing" toolbar: select a range, type a number in the "Value:" field and press a button:

The entered number stays in the field when you move to another map; the field only adjusts its number of decimals to it. The selection is kept; one entry in the undo history; the result is limited to the map's allowed range; unavailable in smoothing mode.

Edit → Rescale Area… (/). A full rectangle of cells is required. The dialog offers the operation (addition / percent / multiplication) and the parameters for the center and the four corners; the "Preview Changes" checkbox shows the result before confirmation. Unavailable in smoothing mode.

Edit → Interpolate (Ctrl+I) — with two or more cells selected in one row or column, the intermediate values are recalculated from the outer ones. One entry in the history.

"Restore Selection to Baseline" is unavailable if the selected cells already equal the original, the map has no baseline snapshot, an error map is open, smoothing is on or a comparison is in progress.
