txtReplace is a tool that can be used to make the web more effective.

It works by allowing you to search your browser window for words in your deck and replace them with other words. This all happens in the background, so you don't need to wait for it to complete when you want to replace a word. You can also set different options for txtReplace to make it easier to use.

You can also use txtReplace with regular expressions.

So if you have a series of words in your deck that are related to something, you can create a regular expression that will search for all of the words related to a subject and replace them with a unique word in your deck.
