Custom overline styles?

[steve-o]

I write a lot of documents with science/math content and would like to be able to use the character overline feature to put arrows and carets over certain characters to show that they represent vectors instead of standard variables. There are many options for the overline style but none of them suit my needs.

I wondered if there is a way I can create a custom overline style similar to the custom arrow styles available in OO Draw. I don't see anything about it... but hoped there might be a configuration file somewhere I can modify that might allow me to put more styles in? The existing styles must be stored somewhere, somehow...

I know that I can create one-character formula objects and keep them inline with my paragraph, but that seems clumsy to me and would make searching my documents for certain symbols impossible. I'm also aware of an extension called Compose Special Characters which I am going to try but have not done yet. I would prefer to use built-in functionalities instead of extensions if possible.

Can you manage it as a formula object?: vec A gives

You may use combining characters: a⃑ is done with U+20D1 and a simple a, a᷍b is with U+1DCD and two characters... and so on.

Combining Character on Wikipedia

On Linux systems and with a GTK interface you can use Ctrl-Shift-u (an underlined u will be shown) type the unicode numbers and press enter. You can also use Compose Special Characters extension to insert arbitrary unicode symbols.
