What is the function of the lock-icon in the tabs (IDE)
It is to make you laugh. If the tab is unlocked you don’t have a searchbar. But you can still double-click on a method to open the same tab twice. Which makes me laugh and groan all the time.
This may help:
Hmm… OK …
Tabs can be locked or unlocked. A locked tab will not have its contents changed when you click on Filter or Search results, nor will it be changed when you use Go To Location. In those cases, a new tab (or the next available unlocked tab) are used. Click the small x in the tab to close it. Hold down Option (on Mac) or Alt (on Windows or Linux) when clicking the “x” to close all tabs but the left-most one.
If you open more tabs than can be displayed in the tab bar, an overflow icon appears for you to click to get a drop-down list of the remain tabs. Select a tab from the list replaces the currently selected tab. You can switch between tabs (wrapping around at the beginning or end) using ?+Shift+[ or ?+Shift+].
Navigator and Tab Locking are basically broken, IMHO: sometimes it works, sometimes it doesn’t. There are a lot of feedback cases enterd on this such as <https://xojo.com/issue/28510> <https://xojo.com/issue/25750> <https://xojo.com/issue/46383> <https://xojo.com/issue/24383> <https://xojo.com/issue/27715> <https://xojo.com/issue/37976> <https://xojo.com/issue/27095> <https://xojo.com/issue/28562> and many others…
