1C:Enterprise provides extended functionality for storing numbers in the clipboard. In addition to simply copying a number to the clipboard, you can add numbers to values stored in the clipboard or subtract numbers from them.
Normally you can use the M, M+, and M- buttons of the standard command bar to do this.
To copy a number to a clipboard, select it and then click M (or press Shift + * on the numeric keypad).
To add a number to a value stored in the clipboard, select it and then click M+ (or press Shift + Plus Sign on the numeric keypad).
To subtract a number from a value stored in the clipboard, select it and then click M- (or press Shift + Minus Sign on the numeric keypad).
These operations are available in all forms, and they can also be performed in tables. In a spreadsheet document, you can perform an operation on multiple cells: for example, you can select multiple cells and then copy or add their sum to the clipboard.
You can use the result stored in the clipboard in any form, for example, you can paste it by pressing Shift + Insert or by clicking the corresponding menu items.
You can view a number stored in the clipboard in the formula calculator mode, in the M= field.
If you want to paste a number from a 1C:Enterprise application to the Windows calculator or to a Microsoft Office Excel cell, store it to the clipboard using M, M+, and M- commands instead of regular commands that copy a value to the clipboard.
When you paste a number to a formula calculator, it is pasted in the format defined by the regional infobase settings but without group separators and without replacing decimal separators with decimal points.
When you paste a number to any other target, it is pasted in the format defined by the regional infobase settings but without group separators.
