I do a lot of copy/pasting of paths in Terminal for svn commits, and I've noticed some strange behavior that I can't quite seem to track down. I use cmd-shift-double-click to select the full path from an svn status, and then hit cmd-c and cmd-v in sequence to copy and paste the path into an svn ci that I'm building up. The problem, though, is that sometimes when I hit cmd-c, the computer produces a "click" sound, and instead of copying the path I have selected, it pastes what's currently on the clipboard and send enter, causing my commit to happen sooner than I want.

I can't reliably duplicate the behavior, and I have no idea what's causing it. I'm fairly confident it's not something like having the shift key held down when hitting cmd-c. I have LaunchBar installed with clipboard extensions, but I don't see any configuration options with a shortcut of cmd-c or cmd-v, and looking through my keyboard preferences doesn't suggest anything either. I'm really at a loss, and this sporadic behavior is driving me slowly crazy.

The "click" sound is different from the error sound, right? (The error sound being the beep one heres when, for example, hitting Cmd-C with nothing selected.) And what is the reason for holding down Cmd-Shift while double-clicking? – Arjan Feb 15 '10 at 21:00
Yes, the sound is different from the error sound. Holding down cmd-shift while double-clicking changes the selection behavior. Normally wont's select a full path when double-clicking, but if you hold down cmd-shift and double-click it will. I think the functionality was intended for opening links from the terminal, but it works well for this, too. – user28104 Feb 16 '10 at 18:49

I also have LaunchBar installed and it would occasionally do the same thing using cmd-c anywhere. To solve this I switched off 'Enable ClipMerge' in preferences. I don't know why it does this, it just does.

I'm pretty sure this is the problem, and I've gone ahead and disabled ClipMerge, which I never intentionally use anyhow. Thanks! – user28104 Feb 16 '10 at 18:46

First try to remove LaunchBar with clipboard extensions and see if the problem goes away. If it does, complain to the developer. If it doesn't, try getting a new keyboard.

As for a new keyboard: what erroneous keystrokes could the current keyboard be sending that explains the behaviour? – Arjan Feb 15 '10 at 20:58
