## Formula Tips

We probably spend the majority of our Excel lives writing and modifying formulas. They are the heart of Excel, and amazingly powerful!

Formulas can also be frustrating, overwhelming, and difficult to figure out. So, in this post I share five tips & shortcuts to help you read and write formulas faster.

## #1 – Enter & Edit Modes with F2

When you have a cell selected, pressing the `F2` key puts the cell in Edit mode. If the cell contains a formula, you will see the formula in the cell and be able to edit it. This is the **same as double-clicking the cell** with the mouse.

But there's more to it…

Sometimes you might want to **select a cell/range with arrow keys** to change a reference. When you press the arrow keys in Edit mode, the text cursor moves within the formula.

At this point you can **press F2 again** to put the formula in **Enter or Point mode**. Now the arrow keys will select cells instead of moving the text cursor.

The **mode is displayed in the bottom-left corner** of the application window in the Status Bar.

You can press F2 again to toggle back to Edit mode, to move the text cursor. This **toggle allows you to modify formulas by just using the keyboard**.

The use of F2 will depend on the scenario. Sometimes it's faster to use the mouse. However, Enter & Edit modes make it very easy to select text or ranges with shortcut keys like `Ctrl`+`Shift`+`End`.

## #2 – Absolute & Relative Reference with F4

If you find yourself typing the $ symbol to create absolute/relative references, then the `F4` key will quickly become your new best friend.

After creating a range reference in a formula (with either the mouse or keyboard), pressing the **F4 key will add the $ symbols** and make the reference absolute.

The F4 key is a toggle that will cycle through all absolute, mixed, and relative reference states.

- 1st press – Full Absolute Reference:
**$A$2** - 2nd press – Absolute Row Reference:
**A$2** - 3rd press – Absolute Column Reference:
**$A2** - 4th press – Full Relative Reference:
**A2**

You can continue to press F4 to cycle through these states. The cycle will start at the existing state for the reference and change to the next when you press F4.

**F4 also works on range references ($A$2:$A$10).**

When you first create the reference by selecting it with the mouse or keyboard, press F4 to make apply the change to the full reference.

If you modify an **existing** range reference then you will need to **select the entire reference** before pressing F4. Otherwise it will only modify the part of the reference that the text cursor is in.

I share a quick way to select the entire range reference in the next tip

## #3 – Select Argument Text with Screentip Hyperlinks

Sometimes it's difficult to find and modify arguments within complex formulas. We can use the function's screentip hyperlinks to help with this.

When you put the text cursor inside a function, a screentip appears below with the function's arguments. Click the hyperlink for any argument to select the argument's text in the formula.

If you are modifying the absolute/relative reference of the formula, then you can press F4 directly after clicking the link.

**Bonus tip: **If the function screentip is in your way, you can also move it by hovering the mouse over the border until the cursor turns into a cross arrow.

## #4 – Evaluate Formula Components with F9

When dealing with long and complex formulas, you might want to see the results of a nested function/formula (a formula within the formula).

Select the text within the formula that you want to evaluate, then press the `F9` key. Excel will calculate the selected text and return the result direct to the formula.

This can help you step through and understand how a formula calculates, but there are a few important things to know.

- You must select the entire expression or function. If you only select part of a function's text then Excel will show an error message.
- Press
`Escape`after evaluating parts of the formula.**This is important!**Escape will exit out of Edit mode and not commit the changes.

If you press Enter then the results of the evaluation will be committed to the formula, and you will lose the parts of the formula you evaluated.

The F9 shortcut works well when you are trying to figure out what a specific component of the formula is calculating. The next tip explains how to step through the entire formula.

## #5 – The Evaluate Formula Window

The Evaluate Formula Window is a great tool if you've inherited a workbook that contains complex formulas. It allows you to **step through each component of the formula** and see how it calculates.

Here's how to use it.

- Select the cell that contains the formula you want to evaluate.
- Go to the Formulas tab in the Ribbon and press the Evaluate Formula button. (keyboard shortcut: Alt, T, U, F)
- The Evaluate Formula window will appear with the formula loaded in the Evaluation box.
- The
**underlined expression**within the formula will be evaluated next. - Press the Evaluate button, or the
**Space Bar**, to evaluate the expression and see the result in the formula. - You can continue to press Evaluate or Space Bar to evaluate each step.
- You will eventually see the result of the entire formula. You can then press Restart or Space Bar again to start over.
- You can close the window at any time during the evaluation process. The window
**does NOT change the formula at all**.

If you find yourself stepping through the formula several times, then you might want to switch back to editing the formula and use the F9 shortcut. I often use both of these techniques when learning or debugging a complex formula.

## Function Lock on Laptop Keyboards

At the end of the video I mentioned a tip **if the function keys (F1-F12) are not working for you**. This is typically due to your keyboard having multi-purpose function keys, which is common on laptops and smaller/newer keyboards.

If that's the case, you will have to press the Fn key in combination with the function key. This can definitely **slow you down**!

Fortunately, many keyboards have an **Fn Lock feature** that allows you make the function keys the primary command. You can usually do a quick Google search with the model name of your keyboard/laptop and the phrase “fn lock”, to see if it is available. All manufactures handle this differently.

As a last resort, you can also modify the BIOS to lock the function keys. This is not a permanent change, but harder to toggle on/off quickly.

Hi. I’m trying to comment on the other post but it says can’t find the page or following an expired link. Did anything change?

I mean the convert text to dates page – I wanted to share a user defined formula that solved the problem

Hi Jon,

It’s Sumon from Bangladesh. I have a functional problem. I want to multiple a Minimum value from a table with another cell. but I filed to do this by MIN function.

=IFERROR(P6<=1,"",((MIN(IF($C$5:$C$39=$N6,$E$5:$E$39)*P6))))

It's my formula. please help me to solve my problem.

Thank you
