LaTeX: is it possible to create a macro to add words to index (using TexMaker)?

Question

I'm just finishing my first document (a book), and I have to create an index (\makeindex, \printindex, \index{WORD}, ...).

I am using TexMaker on Linux.

I was wondering if it's possible to define something like a "macro", to be able to avoid adding \index{WORD} before each word to be indexed (my document will have very many words to be indexed... :-).

I mean, I'd like to be able to define a command which would allow me - clicking a keyboard short-cut, for example [Ctrl][F9] - to insert \index{WORD} just before the WORD the cursor is on...

Skimming through TexMaker docs, I couldn't find anything useful to that intent...

UPDATE I am following the suggestions in the comments, but I can't yet fully understand how to solve my problem... Feel quite dumb right now... :-(

So: I add the command \iindex in my book heading, as Sigur suggested:

\newcommand\iindex[1]{#1\index{#1}}

So far so good. Now I would like to associate a keyboard shortcut to it. As suggested (always by Sigur) I look for a macros menu, but I can't find it (I use Texmaker 4.0.3).
As suggested by Aradnix, I open the User menu, and find these sub-menus:

• User Tags
• User Commands
• Customize Completion

Both Tags, Commands can be customized, but I suppose:
- Commands are for external commands (not my case).
- Tags are more promising, but what do I write in tag's LaTeX content? I mean, how do I refer to the word under cursor, which I want to index?
- Customize completion lists items already defined (which include for example \index{•}), and I can add new commands; but, I can't understand how to associate it with a shortcut... :-).

Any more literal suggestion for a LaTeX newbe...?
If anybody solves and answers, I will accept the answer, of course... :-)

Answer 1

Having added the suggested \newcommand to the preamble, you can add a user tag with

\iindex{@}

as 'LaTeX Content'. Using the default shortcut, e.g. Shift + F1 if the first tag was chosen, will insert \iindex{•}, or if a word was selected, it will replace word with \iindex{word}.

I don't know if it is possible to change these shortcuts, I didn't see anything in Options --> Configure Texmaker --> Shortcuts.
