Move only 1 candle at a time for testing on MT4

So I like to visually test my strategy...I want to make decisions of Buy/Sell or adjust SL and TP at every bar. For this I need to move 1 candle at a time on my MT4 terminal. Currently I use the "Right Arrow" key on my keyboard to move to the future. But this moves around 4-5 candles at a time. Can I change some settings so I will move only 1 candle at very press of the key?

Try pressing the F12 key, with auto scroll switched off.

that worked! Thank you very much!
