The answer given for How to get Intellij Idea to display compilation warnings? no longer applies from version 12. There is no longer a messages panel, as far as I can see.
How can I see a full list of all warnings in the project in version 12?
This option and the Messages panel is on the same place as before in IDEA 12.0.3:
If you don't see it, it means that your project has no errors. Make any error and the panel will appear. Verify that Hide warnings is not enabled. Fix the error, Make the project again, you should see only warnings:
Note that Make is incremental, if there were no changes, it will not compile and report any old warnings, so you may need to Rebuild to see all of them.

I'm working on a create-react-app codebase with Typescript enabled.
I find that IDEA real-time syntax analysis of my code often gets "stuck".
I make a mistake, IDEA shows the little red squiggles almost immediately, then I fix the errors but sometimes the red squiggles don't always go away.
For example:
There's nothing wrong with the above code any more, but IDEA still shows the red squiggles, both in the code and the project tool window / changelist window.
I've found that I can "un-stick" the code analysis by killing any/all the node.exe sub-process that IDEA has. Presumably one of those sub-process is "stuck" and when I kill the process, IDEA launches a new one and the syntax error highlighting will disappear.
Obviously, I'd prefer that the code analysis not get stuck at all, but failing that is there a way I can "un-stick" the code analysis from within the IDE?
I'm looking for something faster than re-starting IDEA (or clearing caches, etc.)
Using IntelliJ IDEA 2020.3 (Ultimate edition) on Windows.

As per comment from Lena, restarting the Typescript language service will fix issues with stale highlighting errors.
The Typescript status bar widget is usually found at the bottom right of the editor:
Tested with IDEA 2021.1.2
I am working with Itellij IDEA (2017.2.4). I am not sure whether the reason is new version of IDEA, but I started to face it after new version installed.
When I type some code in editor and Tooltip is shown (it can be inspection or just parameters of method shown ect.) I cannot type new symbols until pressing ESCAPE button, it is not useful for me. Before updating the IDEA there was behavior when user types new code, tooltip is hidden without ESCAPE pressing. It was made hidden by any key pressed.
Actually maybe I just change some setting property unconsciously, if yes - what is the property needed to be restored to default?
How to make it hidden not by ESCAPE but by any button?
In next image I pictured the moment when only ESCAPE key can be pressed.
I'm not able to reproduce the issue, even when I use v2017.2.4 on windows. The behavior should be that you can still type even when the tooltip is present:
I can't think of anything in terms of settings that could cause this issue. If it's just the "parameter info" tooltip that is causing the issue, you can disable it (or just increase the delay time) from automatically popping up via the setting: Settings > Editor > Code Completion > "Parameter Info" > "Autopopup" You can then manually open it via the Parameter Info Action via Ctrl+P / ⌘P. The setting #Maciej-Białorucki mentioned will effect the time before other tooltips open. Setting to a high value might help if other tooltips are causing issues.
Personally, I find the auto popup useful. To troubleshoot why this is causing issues, I'd recommend trying the following:
Upgrade to v 2017.2.6 which was released yesterday. While I personally can't reproduce it, and I'm not seeing anything about it in the 2017.2.5 Release Notes nor the 2017.2.6 Release Notes, it can't hurt to try and upgrade.
Disable all third party plugins and restart IDEA. See if the issue persists. In my 14 years of using IDEA and helping people with it on the forums, I've seen 3rd party plugins having bugs that cause other parts of IDEA to misbehave. Since you recently upgraded, it's possible a 3rd party plugin is having a compatibility issue with the new version. If the disabling them solves it, use a binary search to as you re-enable the plugins to track down the culprit and then report the bug to the plugin's developer.
See if it happens in other projects. If not there may be something wrong with the project's configuration. (A long shot. But worth checking out)
As another long shot, you can try invalidating the caches and then restarting IDEA via File > Invalidate Caches / Restart... I have on occasion over the years seen a corrupted index file or cache cause strange behavior.
If none of the above work, I suggest opening a bug report with JetBrains at: https://youtrack.jetbrains.com
Check Tooltip initial delay(ms) option under Appearance in Idea settings.
As I divined there was a property in settings that influences to the behavior described in a question. So to continue writing code without pressing ESCAPE key you must uncheck the following property:
Menu page Settings -> Appearance & Behavior -> System Settings
Checkbox Accessibility -> Support screen readers (requires start)

I want to suppress a warning in my xaml file. I applied the corresponding quick fix option to "Disable once warning by comment". However, the warning
is still active. How do I correctly suppress the warning? I would like to keep the name because it tells something about the purpose of the element. (An alternative would be to remove the name and use a comment.)
Edit
The issue is only valid vor Resharper version Build 8.2.0.2160.
After updating to 8.2.3 the suppression works correctly. (And in version 9 the warning does not seem to be active by default.) Thanks to citizenmatt.
The issue is still shown in the Inspection Results view, see related question Resharper: How to hide suppressed warnings in Inspection Results?
In this special case it makes more sense to use the Tag attribute (thanks to Mike Eason) or to use a comment to write the name instead of using a comment to suppress the warning.
This looks like an issue with an older version of ReSharper. You can update to the latest version of 8.x (8.2.3) or ReSharper 9 (the 9.2 EAP has just released EAP3). It appears to have fixed the issue.
It really annoys me that IntelliJ highlights certain 'errors' (that don't prevent successful compilation) the same way that real errors are highlighted. For example, a magic number is not really an error, but it will be flagged in exactly the same way as an incompatible type error.
How can I change this?
Go to Settings -> Inspections. Then you need to search through the long list for the offending inspection, which you can get the name of by hovering on the warning marker in the margin. You can change the severity of the inspection, whether it's an error, warning, etc. or just disable it altogether.
Edit: if you search for "magic" in Settings, you get the following, which should be helpful:
Whenever you see an inspection warning/error you can place the caret on it and press Alt+Enter (a light bulb also appears that tells you that). A menu will appear with suggested quick fixes. You may need to open a submenu by pressing Right, and you'll find "Edit inspection settings" there. Having invoked that, you may proceed as in hvgotcodes's answer :), it's just a faster way of getting to those settings.
As Michael Calvin said you can use the SuppressWarnings annotation. For example:
#SuppressWarnings("OptionalUsedAsFieldOrParameterType")
See https://github.com/JetBrains/intellij-community/blob/master/plugins/InspectionGadgets/src/inspectionDescriptions/OptionalUsedAsFieldOrParameterType.html
Usually searching the internet for the exact description leads me to this.

I got to this question while trying to figure out how to disable IntelliJ IDEA's warnings about Guava functionalities that have been replaced by Java 8 features. I'm not able to use the Java 8 versions of these features in my case because of a library we're using that was built with Guava (despite being a Java 8 project). So to solve that, I added a SuppressWarnings annotation before any class using Guava:
#SuppressWarnings(Guava)
public final class...
I'm working with Intellij Idea 10 and Java 6 JDK Update 7. When I run Build --> Rebuild Project command, and the (javac) compilation generates warnings, Idea doesn't display what those warnings exactly are in the Messages view. I just see an "Information: XX warnings" node, but no way to expand it to see the actual warnings. Or I just see a message "Compilation completed successfully with XX warnings" on the status bar. For errors, Idea displays the error information (error message, filename, line number etc.) automatically. How can I get it to work similarly with warnings?
(For the record, I've already tried using additional command line parameters such as -Xlint, but it does not make a difference.)
Make sure that "Hide Warnings" option is disabled in the Messages panel on the left:
