Description Aaron Sowry cendio 2022-02-28 00:12:04 CET
In particular, the OS X client has a hard-coded mapping which is not well-suited to some work flows. It would be useful if these mappings were configurable by the user.
Comment 1 Aaron Sowry cendio 2022-02-28 23:23:14 CET
For example, some common keyboard layouts have no concept of AltGr. On OS X both Alt keys are mapped to AltGr, which can be confusing for users who are not familiar with this modifier.

This configuration also makes it difficult to Alt-Tab switch when ThinLinc isn't in fullscreen mode, since the local and remote systems interpret the keypresses differently.
Comment 2 Pierre Ossman cendio 2022-03-01 09:04:53 CET
Unfortunately, because of the AltGr behaviour, disabling this can have very weird effects that will likely be confusing for users. I would suspect that something like bug 4560 would be required to get rid of this mapping.

(The mapping also has the effect of Cmd+Tab on the client being mapped to Alt+Tab on the server, which should increase familiarity for macOS users rather than reduce it.)

This was noted in the community here:


Note that the use case mentioned is really about being able to send all keys to the session in windowed mode (bug 4660), not specifically this issue mentioned here.
