I am doing my undergraduate work in Electrical Engineering and I choose LaTeX as the tool for the job and TexStudio as my LaTeX editor. I had a pretty nice walk through LaTeX, but I begin to wonder what about some advanced stuff such as changing/modifying the handling of existing commands in the editor. My particular need is to make a \begin{myflalign/myflalign*} environment and configure the editor such that it would insert this code:

\begin{myflalign*}
    &  &
\end{myflalign*}

and position my cursor in between two & signs.

I do a lot of aligning and find that this command really suits me well and I only need a slight improvement of an existing command.

    Welcome to Tex.SX. I don't understand your question. Do you want a new environment (myflalign), or do you want to configure your editor to automatically complete an environment and position the cursor? If you need a new environment, what do you want it to do? – Ian Thompson Aug 22 '13 at 22:24
  • This may be editor-specific, and not every editor can/will be able to do this. For a complete list of available editors, see LaTeX Editors/IDEs. – Werner Aug 22 '13 at 22:57
  • Well I guess it is editor specific! And yes I want to configure editor to automatically complete and env and position the cursor... I use TexStudio, do you think this is doable? – Zlatko Alomerovic Aug 23 '13 at 11:00
  • @djudji Did you have a look at personal and environment macros? – ojdo Dec 4 '15 at 17:00

You can define a personal macro (see the manual, Section 4.5). Since you would also like to position the cursor, it should be a script macro. Choose a name and a trigger (I chose myenv as the name and %myenv as the trigger). Whenever you type in the trigger, the trigger text will be removed and the script will be executed. The following script will do the trick:

%SCRIPT
cursor.insertText("\\begin{myflalign*}");
cursor.insertLine();
cursor.insertText("   &  & ");
cursor.insertLine();
cursor.insertText("\\end{myflalign*}");
cursor.movePosition(1, cursorEnums.PreviousLine);
cursor.movePosition(1, cursorEnums.StartOfLine);
cursor.movePosition(5, cursorEnums.Right);

It inserts the beginning of your environment, inserts a new line, inserts the & symbols, another new line, and the end of the environment. Then it positions the cursor by going one line upwards, then to the beginning of the current line, and finally 5 columns to the right to end up between the two & symbols.
