Por algum motivo, algumas chaves enviam apenas um evento KeyRelease e não um evento KeyPress:
Isso é o que recebo quando pressiono o Print Screen. Isso torna a chave Print Screen inutilizável para remapeamento para chaves que enviam os eventos KeyPress e KeyRelease .

Existe alguma forma de obter essas chaves para enviar os dois eventos?
