Also I should add, the absolute fastest way to navigate to a chapter is to just start typing it and add a period. So for example, if I am in Psalms, I just type "10." and the text goes into the main search bar. Hit enter and it will go to chapter ten. If you leave off the period it will go to the tenth verse in the current chapter instead. If you type 10.2 it will go to chapter 10, verse two of the current book. also if you want to go to the next chapter, Alt+PageDn will do that, and Alt+PageUp will go to the previous chapter.
