Description Greg Lepore 2021-06-28 15:05:27 UTC 
Just a general observation, but the KDE Human Interface Guidelines indicate that applications with tabs should:

"Provide keyboard navigation to switch between tabs with Ctrl + Tab (Ctrl
Shift + Tab for backward navigation). For compatibility reasons it is recommended to also support Ctrl + PgDown (Ctrl + PgUp for backward navigation)."

It appears Kate 21.04.2 does not support Ctrl + Tab to switch between tabs. Rather Ctrl + Tab indents the current line. Nor does Kate accept Ctrl + Shift + Tab.

Ctrl + PgDown and Ctrl + PgUp do work as designed.

I guess this is a wishlist request to have Kate fully support the HIG with respect to tabs.

Can't reproduce, Kate switches tabs with Ctrl+Tab just fine.
Comment 2 Paul Worrall 2021-06-29 09:29:31 UTC 
Please could you confirm that your keyboard shortcut config in Kate, under the "tabswitcher" group has: 

> Last Used Views = Ctrl+Tab
> Last Used Views (Reverse) = Ctrl+Shift+Tab

These are the default settings (for me) and they work for me.

Kate->Configure Shortcuts->tab
Comment 4 Greg Lepore 2021-06-29 10:53:12 UTC 
Thanks for checking. I don't have a tabswitcher section in Configure Shortcuts. Next Tab is set to Alt-Left and Previous Tab is set to Alt-Right. Clicking the Defaults button does not seem to change these settings.

Kate Plugins

Do you have the "Document Switcher" plugin enabled? (Settings=>Configure Kate=>Plugins)
Comment 6 Greg Lepore 2021-06-29 11:42:46 UTC 
I do not have the Document Switcher installed. Installing it does make Alt-Tab work correctly, albeit with an onscreen indicator that I don't love.

I wonder if a clean install of Kate does not switch tabs without the Document Switcher? If so, the Wish should remain, as that should be the default behavior.

Thanks.
Comment 7 Paul Worrall 2021-06-29 12:08:51 UTC 
Just confirmed that a clean install of  Kate on vanilla Neon User has the Document Switcher plugin enabled by default, and that Ctrl+Tab does switch between tabs (albeit with that indicator). So on the basis that Ctrl+Tab does switch tabs by default I think this bug should be closed.
