Watch the I Feel Ya online guitar lesson by Jeff McErlain from Soloing the Changes
Of course, there's more to think about than just changing modes or the one note to really dig in to making the changes. Each chord is made up of specific notes that form that chord - these are chord tones. The chord tones are always a safe bet to choose when soloing and the point of this course. Even if I'm not changing keys, I'm thinking about chord tones. As guitar players, we're usually thinking pentatonic, and as a result hit the root of the pentatonic scale a lot. By starting easy, and in this case being sure to hit the F or the F# at the right time, we can start to break out of that habit.
