People who program know that most of the time relies on a editing source code tool. However, how time is divided between the editing tasks remains unclear from the scientific point of view. According to an important study, it was found that approximately 30% of a programmer working time is not spent editing the text (by including, editing or deleting), but surfing between multiple files along the source code. The navigation involves research, observation, information gathering, memoring and other activities. That is, you could say that programming is an activity whose third part is just contemplative.
