Changing MacOS keybindings for Home/End keys to behave the same as Windows

Sometimes muscle memory is hard to unlearn. I can’t get used to the Home and End keys on a Mac jumping to the top and end of a file instead of start and end of a line. Yes, I know Cmd-left and Cmd-right do the same thing on a Mac, but pressing Home and having it jump to the top of a file is too much for me to handle when in the middle of editing something in an IDE like Eclipse.

To remap the Home and End keys to behave the same as on Windows, make a dir here:

mkdir ~/Library/KeyBindings

and create a file called DefaultKeyBindings.dict containing this content:

"\UF729" = "moveToBeginningOfLine:";
"\UF72B" = "moveToEndOfLine:";
"$\UF729" = "moveToBeginningOfLineAndModifySelection:";
"$\UF72B" = "moveToEndOfLineAndModifySelection:";

Logoff and log back on again, and the Home and End keys should now work the same as on Windows. (source here)

If this still doesn’t work in Eclipse, it maybe because Line Start and Line End and explicitly mapped to Cmd-left and Cmd-right – these can be changed in Preferences under Keys:

Delete the existing mappings for Home and End and change to the Home and End keys:

Updating local versions of Docker images if using the latest tag

I have an ubuntu:latest image pulled locally from a couple of years ago, and it’s obviously not the latest since it’s over 2 years old. ‘docker images’ shows:

ubuntu                                                                           latest                     d5ca7a445605   2 years ago     65.6MB

If I run the image with -it and cat the /etc/lsb-release file, it shows it’s 20.04. Docker Hub is currently showing latest as 22.04.

To update it, if I ‘docker pull ubuntu:latest’ then it shows:

> docker pull ubuntu:latest
latest: Pulling from library/ubuntu
70104cd59e2a: Pull complete
Digest: sha256:1b8d8ff4777f36f19bfe73ee4df61e3a0b789caeff29caa019539ec7c9a57f95
Status: Downloaded newer image for ubuntu:latest

If I now start it and cat /etc/lsb-release, it shows 22.04. Done!
