Hi Sharber,
I hope you are keeping well.
Within TestComplete there is the Delay Operation that could be used to pause the keyword test execution for the specified period.

Another approach could be the Wait operation which could be used to wait until a tested object gets an expected property value. This may be useful if an expected event occurs in your tested application only after a tested object goes into a particular state.
For example, in a dialog showing some operation progress, the OK button becomes enabled only after the progress bar reaches 100%.

Please let me know if this resolves your query or if you have any additional questions.
Thanks,
Shane
