I might be being really dense, but it seems that none of the find and replace utilities that I have looked at do quite what I want.

I would like to be able to define a list of standard replacements to make and then store it somewhere, so that when I have a file that I need to do multiple replacements on I can just run it, rather than doing find-replace over and over. 

The particular application:  I have a very long BibTeX file (3500+ entries), some of which are written using the LaTeX codes for characters, and some of which have characters that I put in using ASCII codes, or whatever the places I imported them from used.  Some of them are causing problems when I try to compile the document, and I would like to go through and replace them all with the codes.  I anticipate having to do this more than once, so it would be nice to have a ready-defined list to run.  It only needs to be one file at a time.

The list would be something like:
find  replace
á      \'{a}
Á     \'{A}
é      \'{e}

And so on.  Lots of programs seem like they will do this, but I can't figure out how to avoid typing in the list over and over again.

Sorry if it is a dumb question...

Apologies if this is misplaced and/or obvious.

Is it possible to combine all the AHK scripts and programs in such a way that there is only one taskbar button, and right-clicking on it would allow you to navigate to the program you want and then access the menu for that program?  Sort of like a miniature program launcher or start menu, only in the tray.

DesktopCoral sounds like it could be useful for me sometimes, but I don't understand how to put things into the dock area.  Dragging shortcuts from the desktop doesn't work, and there don't seem to be any instructions.

What am I missing?
