Daily Dose of Excel

Did you ever stop to think of what goes on behind the scenes in Excel when you enter something into a cell? I came up with a rough list:

First keystroke:

• If the cell locked and the sheet is protected, display error
• Update the formula bar and/or the cell
• If it's an equal sign, at symbol, minus sign, or plus sign change status bar and Name box
• Disable inappropriate menu items
• Suggest Autocomplete, if possible and enabled

Other keystrokes:

• Update the formula bar and the cell display
• Monitor keyboard for things such as Ctrl+B and Ctrl+I
• Monitor keyboard for things such Shift+F3 to insert a function
• Monitor toolbars for formatting changes
• Suggest Autocomplete, if possible and enabled

Enter key (or arrow key):

• Check for valid formula and display error or pop-up
• Check for names used
• Check for external references, and retrieve values if necessary
• Check for dependent formulas and recalc if necessary
• Check the 1-2-3 formula evaluation setting
• Check for data validation
• Check of conditional formatting
• Check the AutoCorrect list and adjust if necessary
• Check if the cell has a style, and adjust appropriately
• Check to see if it's part of an array
• If it's a number, display it using appropriate number format
• Display it using correct alignment
• Display it using correct font, size and attributes
• Adjust row height, if necessary
• Autoadjust column width if appropriate
• Update formula bar
• Check for a VBA event-procedure (e.g., Worksheet_Change)
• Check if it's a hyperlink
• Activate next cell if appropriate
• Display formula error SmartTag if necessary
• Check to see if the cell is in the Watch list
• Check to see if cell is contained within a camera tool picture
• Update charts, if necessary
• If text-to-speech is active, speak the cell contents

What have I missed?
