Actually both software has been developed for many years and even today they are still advanced over modern system tools. I find them especially helpful for researcher, who quite often need to search documents and papers, and write something with repetitive phases (e.g. species name). Here comes the two tools:

If you have a lot of files stored on your PC and often you need to find something, Everything will be ideal for you.

For instance, to insert special characters with a single keystroke, to disable your touchpad while typing, But more often, it’s been used to shorten any phrases or URLs (‘sma’ for Schistosoma mansoni; ‘gbb’ for https://www.genedb.org/SequenceDistributor/Smp_/PROTEIN/NCBI_BLAST) and auto-correct mistyped words.

AutoHotKey is also light (3.1 MB) and completely free.
