I often need to rename longer filenames in Finder. I used to do Shift + Command + ←/→ to select text from cursor to the start/end of the field.
But in macOS Mojave, suddenly this combination started to switch to previous/next Finder tab - so when I use the shortcut, file name editing is cancelled and I get switched to a new tab.
This doesn't happen in macOS High Sierra, and it's described in Apple's support document, Mac keyboard shortcuts as:
Shift–Command–Left Arrow: Select the text between the insertion point and the beginning of the current line.
Shift–Command–Right Arrow: Select the text between the insertion point and the end of the current line.
Is this a bug? Is there a known workaround?
