Reference operators 4/3
Session Links
  • Colon
    Same as “the rectangular region including both”
    • A2:B7 means “the minimum rectangular region including both A2 and B7
  • Comma
    Same as “and”. Thus A1:A2,B1:B2 is a reference to a range with two areas and four cells.
    Surround with parentheses for safety and readability: (A1:A2,B1:B2)
  • Space
    Same as “intersection”
    (A1:B3 B2:C3) is the intersection (B2:B3)
    Surround with parentheses for safety and readability

These three operators are useful for extracting specific regions. One is very familiar to you: the Colon. The other two, respectively, produce the Union of two ranges and the Intersection of two ranges.

Unlike the Colon operator, the Comma and Space operator are “nary”, which means that you can string together an arbitrarily long number of arguments. For example, if RangeA, RangeB, RangeC, and RangeD are ranges, then the formula

=RangeA RangeB RangeC RangeD

returns the intersection of all four ranges.

The intersection operator and union operators don’t work with 3-D references.

Avoid Unnecessary Spaces in Formulas

The space character, in many cases, doesn’t change the value of a formula. For instance, these two formulas return the same value:

  • =A1 + 2
  • =A1+2

Some people think that well-placed spaces make formulas easier to read. Although that might be true, the practice is both inconvenient and extremely dangerous. More

Keyboard Power Tips

Excel’s online help, and many of the how-to books you can buy, provide long lists of keystroke shortcuts for carrying out specific operations, such as inserting rows, selecting regions, or deleting columns. And they are useful.

But the true power of the keyboard comes not from using these particular commands. Rather, it comes from learning combinations that are useful for particular situations that you encounter frequently.

For instance, there’s no command for deleting the rows that contain the selected cells, but there is a combination:

  • Shift+Space selects the rows that contain the selection.
  • Ctrl+- deletes the now-selected rows.

And so, Shift+Space Ctrl+- deletes the rows containing the selection.

Learning a vast array of keystroke commands is probably less useful than learning the keystroke combinations that do exactly what you need to do most often.
