What on earth are you talking about? The whole point of all these tools is to reduce the amount of key presses needed. Why do you think ed -- the standard text editor -- was conceived? I jest but this is kind of the whole point of modern computer interfaces vs typewriters and punch cards. Historically it has _absolutely_ been a bottleneck, and I feel like it's being taken for granted that you can search-and-replace or use sed or your IDE's context-aware renaming/refactoring.

Have you even used macros in vim (or whatever)? It's practically a modern editor's raison d'être.
