I have a very basic, conceptual question. I come from a lot of experience with LaTex, however at my current workplace nobody else cares about it. Now it is time to write my thesis and I am looking for the middle ground between the horrors of MS Word and the elegance of LaTex that comes without an user interface. LyX seems to be the obvious choice, combining GUI and tools like follow changes with the power of underlying Latex.
My issue though: Why is everything so mouse heavy? Is there a way to make LyX usable by 90 % keyboard? LaTex is nice and clear and concise and I can type complex structures without taking my hands of the keyboard. I'd love to have the same convenience from LyX.
Example: I have to type Cyt b _6 f (subscript 6) a lot in my thesis. In Latex I would either just type "cyt b$_6$f" or define a command in the header an get it by typing \cytbf. In LyX I have to grab the mouse and move to "Insert->Formatting->Subscript" without slipping with my mouse into another hover-sensitive menu.
Is there a better way? There has to be. I know that I can define code chunks before hand, but if my subscript letters change often enough it doesn't help me at all.
I am sorry for the very basic question. I hope somebody can help and make LyX attractive for me because I'd really like to like it.

a_bto getawith a subscriptb. Or Alt + M X to insert a math subscript directly. In general though, there are a lot of keyboard shortcuts I think.
