I use a third-party external keyboard with my MacBook Pro. It's a
ThinkPad USB keyboard with Trackpoint(I love having control of the mouse pointer without having to move my hands off the keyboard).
Just one problem: one particular key combo doesn't work. In a text editor,
option + shift + right-arrow should highlight the word to the right of the cursor, something I use all the time in programming.
But it does nothing. I know it's a problem specific to the keyboard and not to a particular app, and I also know it's not a simple hardware problem:
Right-arrowworks (moves cursor one character to the right)
Shift + right-arrowworks (highlights the character to the right of the cursor)
Option + right-arrowworks (moves cursor one word to the right)
Option + shift + LEFT-arrowworks (highlights the word to the left) so it's not that this keyboard generally can't handle two modifiers at once;
Option + shift + right-arrowworks on other keyboards (e.g. my cheap Logitech K120) on the same computer and text-editor app (so it's not a system- or app-level keyboard-shortcut-configuration issue)
- Update: It turns out that
Option + RIGHT-shift + right-arrowworks (all the above were tested with left-shift). Unfortunately that's a more awkward hand position for quickly moving your selection point around the screen. Maybe if I found a way to swap the mapping of the two shifts....?
I've observed this on two different MBPs (one bought in 2010 running OS 10.6.8, the other in 2014 running 10.9.4). Some intensive googling turns up nothing as specific as this problem. Has anybody observed and solved a problem like this?
I should have mentioned that I use System Preferences->Keyboard to map the keys printed with "Alt" (closest to the spacebar) to
Command, and the "Windows logo" key to
Option, so that the layout is most like a mac keyboard.
If I swap back (Windows logo =
Command, Alt =
Option) then the problem is simply reversed: now I can do
option + shift + right-arrow (select to end of word) again, but not
command + shift + right-arrow (select to end of line). So the problem is specific to the Windows-logo key location, not to the logical role of Command/Option.
There's no right-hand counterpart to the Windows logo key, so no right "Option". There is, however, a right-hand shift key: see point 6.
