On average, mouse movements can be carried out some 30% faster using keyboard shortcuts (Lane et al., 2005; Tak, 2007). Despite that, 66% of computer users do not use any shortcuts and are very dependent on their computer mouse (ECDL, 2011). Intuitively suggesting and cognitively learning keyboard shortcuts is therefore a must.
With discomfort and injuries such as carpel tunnel linked to or made worse by mouse use reducing mouse use by 50% offers huge health benefits. This applies to proactively preventing discomfort and injury as well as recovery.
