I ran into an interesting issue this morning after running system updates on my main desktop computer (running Arch Linux with the KDE Plasma desktop). For some reason, although I don’t think any behavior was intentionally changed by the developers (and I’m not blaming anyone), Konsole (a KDE terminal app) started intercepting the CTRL+B key combo that is used by tmux. It turns out that this is a standard “Add Bookmark” shortcut in the Plasma desktop environment.
My solution was a bit of a hack, but works for now: I went to System Settings – Shortcuts – Standard Shortcuts, and disabled the “Add Bookmark” shortcut entirely, as I don’t really use it. Problem solved! Now, back to software development…
