Next/Previous Tab on Mac Consistent At Last

After blogging about the inconsistency of keyboard shortcuts for Next/Previous Tab on Mac last year, I found out that Firefox, Thunderbird, and Komodo also support Command + Option + LeftArrow|RightArrow, and Adium has a General > "Switch tabs with" pref that I can set to the same chord.

(Later, I switched IM clients from Adium to InstantBird, which also supports that combination.)

That left Terminal, which I couldn't figure out how to configure to support the same shortcut. Until now.

I'm not sure if it's because I have since upgraded to Mac OS X 10.7 (Lion). I could've sworn I tried something like this back when I wrote that previous blog post, and it didn't work.

1. Go to System Preferences > Keyboard > Keyboard Shortcuts > Application Shortcuts.
2. Press the + (plus) button.
3. Select "Other..." from the Application menu and select Utilities > Terminal from the file picker dialog.
4. Enter "Select Next Tab" (without the quotes) into the Menu Title field.
5. Focus the Keyboard Shortcut field and press Command + Option + RightArrow to set the keyboard shortcut, which will appear as ⌥⌘→.
6. Press the Add button.

Repeat steps 4-6 with "Select Previous Tab" and Command + Option + LeftArrow, which will appear as ⌥⌘←.

Those shortcuts should now work in Terminal.

With this change, all five of my current primary productivity applications on Mac (Firefox, Thunderbird, Instantbird, Komodo, and Terminal) support a consistent pair of keyboard shortcuts for Next/Previous Tab, which are two of the most common commands I issue in all of those apps.

Woot!

generating a fingerprint for an SSH key

After recently discovering a security vulnerability that allows an attacker to add an SSH key to a GitHub user account, GitHub is requiring all users to audit their SSH keys. Its audit page lists one's keys by type and fingerprint, but it doesn't say how it generated the fingerprint or how to generate one for your local copy of a key to compare it with. Nor does it let you see the whole key.

And since I don't generate such fingerprints very often, I didn't know how to do it. So I tried cksum, md5, and shasum on my Mac, but none of their checksums matched. Turns out the tool to use is ssh-keygen:

    ssh-keygen -l -f path/to/keyfile
