How to disable text drag delay

Solution 1:

I think the default is 1 second, which is far too long for me. I find 100ms better.

defaults write -g NSDragAndDropTextDelay -int 100

should work just fine.

Apps need to be relaunched after changing that value.

Setting a negative number will disable drag altogether; zero sets it to immediate.

Solution 2:

With Tinkertool this can be done…

TinkerTool is an application that gives you access to additional preference settings Apple has built into OS X. This allows to activate hidden features in the operating system and in some of the applications delivered with the system.

To further guarantee that the tool cannot change any part of your installation, but only gets access to your personal preference settings, the program puts itself under the restrictions of Apple's Application Sandbox. TinkerTool is the first application of its kind to use this innovative technology.

When you have defined your preferred set of “pro” preference settings, you can additionally export and import the settings, copying them to another user account or to a different computer. All settings which don't depend on the availability of third-party applications can be transferred.

Because TinkerTool only gives you access to features already built into OS X, its feature set varies greatly between different operating system versions.
