Going back and forth between the mouse and keyboard is tedious — aren't there shortcut keys so I can operate with just the keyboard?
Literal
Mouse [and-と] keyboard [object-を] back-and-forth do [nominalizer-の][subject-が] tedious [reason-ので], keyboard only [with-で] operate-able [purpose-よう] shortcut-key [topic-は] not-exist [polite wonder-のでしょうか]?
行ったりきたり 'going back and forth' is a paired ~たり pattern for repeated alternation. 煩雑 'tedious, cumbersome.' ~のみで 'only with' — のみ is a formal-register alternative to だけ. ショートカットキー is a loanword compound. A practical tech question.
