Unintuitive toolbar actions.

[bartek]

Case 1:

Create empty .tex file. Click one of the toolbar buttons. Caret should navigate after opening brace (for bold/italic/underline) or after first closing brace for flush left/right center.

Case 2:

Type some text and select all / some part. Click one of the buttons once, and then again - the same button. It should "disable" current effect, but it's getting doubled.

Suggestion:

Let's have an example:

\textbf{L}a\textbf{T}e\textbf{X} is cool

After moving cursor into first "L", "Bold" button should be "active".
