Frequently Asked Questions

Q. What are Ctrl+Shift+2 and Ctrl+Shift+6 for?

A. Time format and scientific notation, respectively. Less frequently needed, but useful in the right context.

Q. Does changing the number format change the underlying value?

A. No. Only the display changes. The actual stored value is preserved.

Q. I applied a date format but it still shows as a number.

A. The cell may contain a text string rather than a real date value. A display format change alone won't fix that — check the underlying data type.

Q. How do I memorize Excel shortcuts faster?

A. Reading alone won't make them stick. Use KeyboardGym's Excel practice mode to actually type the keys and alternate between sequential and random practice for faster retention.
