Here is a description of the tool that I copied and pasted from the above-mentioned page:
This module provides the functionality of maintain a history cache for Copy actions. This history cache can be accessed for the user, which can select the appropriated String which will be pasted in selected editor.
It is possible too define the cache size, by the appropriate option in Tools > Options > Miscellaneous > Copy and Paste History.
Although this module does sound practical, it brings up the question of just how much copying and pasting developers should be doing. Copying and pasting is often a way to accomplish a goal quickly in the short term by duplicating code, but which leads to less maintainable code in the long term. How do you think developers should use copy and paste?
