As I said, in NX 8.5 it can be launched with one extra action, think of this as the 'ON' button, and once you're finished, selecting the 'Esc' key will turn it 'OFF'.
That being said, even without waiting for NX 8.5, you could go into Customize today (in NX 7.5) and add a shortcut or 'Hot-Key' to the...
Tools -> Assembly Navigator -> Find Selected Component...
...menu item whereby making THAT 'Hot-Key' in essence your 'ON' button and the 'Esc' key would be your 'OFF' button. How does that sound?
To test this, using NX 7.5, I went into...
Tools -> Customize...
...selected the 'Keyboard' button at the bottom of the Customize dialog, and then in the 'Categories:' section of the dialog I navigated down to
Tools -> Assembly Navigator and then in the 'Commands:' section I found and selected
Find Selected Components.... I then in the 'Press new shortcut key:' entry I entered the letter 'c'. I then changed the 'Use new shortcut in:' to 'Application Only' and then hit the 'Assign' button. Then I closed this dialog and then the Customize dialog.
Now all I have to do is press the 'c' key and the 'Find Component' dialog opens and I'm good to go. Then I just press the 'Esc' key to close the dialog.
Note that to save this change to the user interface so that it will never be lost, you will need to resave your current Role.
For now, I can't make it any simpler than that.
