EDIT: Thank you for pointing that out. In Windows 10 the "Replace" dialog has underlined accelerator shortcuts for - _F_ind Next - _R_eplace - Replace _A_ll which are obvious and visible in the dialog. Having to tap alt is lousy UI, and frankly results in an ugly and cluttered appearance --- the underlines were able to communicate the functionality well, and far less obnoxious. EDIT: Hopefully Windows 11 will develop a way to visually communicate this sort of functionality, as opposed to expecting folks to read a (non-existent) manual or randomly tapping keys.
