Any way to prevent emacs key bindings to bug in Eclipse? - eclipse

I'm wondering if I'm the only one struggling (i.e. failing) to keep the emacs key bindings working in Eclipse.
I set them. It works fine. The it stops working fine. Some keys still work, others don't. I find myself in a kind of weird quantum state of uncertain key-binding setup superposition. Some key bindings from the standard set work, some from the emacs set work, some things I can achieve with neither set of bindings.
I'm the only one to experience this? I've seen this on at least 4 computers in the past few months.
I set key bindings back to standard set. Sometimes it works. I use the reset to defaults button. Try to set it back to emacs. Doesn't work. Pressing the apply button between the different steps or not... Drives me crazy.
On some computers, the bindings are just whatever. Can only save using the mouse, C-d and C-k don't work to delete/cut lines, most emacs keys still work but back to C-space for auto-completion, etc.
Anyone knows what can cause this? How to prevent it? Am I pressing some key binding key-bindings by mistake?

I had a similar problem with the Ctl-K, Ctl-D commands: after doing an upgrade (I forget whether it was Eclipse itself or the Android plugin) I saw Eclipse offering a little pop up menu on both these keys, offering to do either the correct Emacs command or some completely unrelated command. So, for example, Ctl-D offered to either delete the next character (correct) or delete the line (incorrect).
After some poking around in the key bindings (Windows>Preferences>General>Keys), I discovered that sure enough, someons in the Eclipse project supplied these wrong bindings in addition to the correct ones. So I deleted the incorrect bindings and left the correct ones.
So I thought I would be out of the woods at this point. But I also discovered that I had to add the correct binding back in a couple of times before it would stick.
Look for Cut to End of Line under the Command column and make sure it has Ctl-K when Editing Text and in the Text Editing Category. The same for Delete Next (which means next character). But make sure Ctl-D does NOT show up for the Delete Line Command.
Test it out in an editor window; if it fails, go edit the bindings again, test again, repeat until it sticks, making sure you click Apply after editing the bindings.

Disabling shortcuts in insertion mode with vim bindings

I am quite new to vscode, and am trying to figure out how to solve the following issue:
I use vim bindings (via vscodevim), and am happy with it
I have custom bindings for the main language I develop in (Coq) that I am adamant about keeping and that are of the form ", n", ", u" and so on. These shortcuts are not used to edit code, but rather to interact with the prover.
This setup currently entails that I globally cannot type a comma anymore, which is quite annoying :) I hence would like to disable these shortcuts when in insertion mode.
I have tried to add the condition !vim.insertModeKeyBindings to all When fields of these custom bindings, but it does not seem to be sufficient: pressing , still triggers a Waiting for second key of chord... even in insertion mode.
Would anyone know how to solve this issue by any chance?
Best,
Yannick

Smart Caret in Eclipse stops working for some files

I am using Eclipse and I am coding java. I really like the "Smart Caret" option for the Home and End buttons since it allows you to go the start and end of a line but not past any whitespaces. Also the Home key will take you to the start of a comment, rather than the start of the line. And you can cycle through different positions with these keys. And this is how the editor was by default, from installation.
However one thing that has happened a few times now is that when I am writing code in the editor, this functionality just vanishes. It is seemingly random when it happens and the weirdest part, I think, is that it is file specific. So all of a sudden when I am writing, the Home and End keys start taking me to the very start and end of the line I am on. It is as if I am accidentally pressing some hotkey to disable these Smart Carets for the specific file.
It does not help to disable and re-enable the Smart Caret option in Preferences. And beyond that I do not really know what to do. Is this a bug? It is incredibly annoying when it happens. Being used to things working one way, then having them spontaneously change and then again having them back to the default when I am editing a different file.

Special keys in Eclipse Issue - IDE always asks for confirmation

Last days I have an issue with eclipse when I press special keys inside the eclipse
IDE.
e.g when I press Ctrl+C
then a small window appears on the bottom right corner of the IDE which
is like this:
Copy | Ctrl+C
The same is for other keys.. I got:
Inline Editing|Enter (when press Enter)
Paste|Ctrl+V (when Ctrl+V)
It is really slowing down typing because it gets the focus and need confirmation clicking
on the right part of the small window.
Does anyone know how can I fix it?
Thank you!
The pop-ups you are seeing are the "keybinding conflict" popups. These are common when you have two different plugins defining the same keybinding and looks like these. This may happen if you installed some plugin which attempts to override the default bindings.
You may investigate your current bindings using "Window>Preferences>General>Keys". Enter the binding (eg. "Ctrl+C") in the filter field (it has "type filter text") and see all the commands that have this key combination bind to. If you have two different commands with same "When" parameter, then there's a conflict.
You may "unbind command" and then bind it again. Or try using "Restore command" button.
Also you may try to un-install the ill-behaving plugin, if you don't need it actually.

About usability issues for Eclipse's auto completion

Recently, I need to use Eclipse instead of Netbeans.
I find the following issues is annoying in my case. Say, I key in the following wrong method name.
So, I tend to fix the error, by deleting the wrong method name (But not parameter, as I know I want to pass in true), including the dot. I key in dot again, Eclipse auto completion will prompts me list of methods
I am happy with the suggestion. I press ENTER. However, this is what I am getting.
Now, I need to manually deleted the uselesss (checked). This is pretty annoying, especially when the method takes in 4 to 5 parameters. I have to delete them 1 by 1.
I consider this a usability defect. I do not have such issue in Netbeans. Anyone of you know any workaround to overcome this usability issues? Is there any options I can turn on or turn off?
You can also press Ctrl+Enter to insert the completion which will 'replace' the incorrect typed word.
Look for "Toggle between inserting and replacing content assist" in http://help.eclipse.org/indigo/index.jsp?topic=/org.eclipse.jdt.doc.user/tips/jdt_tips.html

Emacs - cursor misalignment, and disappearing text

I've been using a copy of emacs (in a Debian VM I ssh to with putty) at work for a couple of months now, and up until now everything has been working brilliantly... but this morning I'm trying to edit a file in shell-script-mode, and am seeing some weird behavior with text around the cursor.
Basically, when I type the following ( [ ] represents my cursor):
export DATABASE[]
After I've typed the first few characters of the variable name the export statement disappears and the variable name aligns to the left margin, and all I end up seeing is (with the cursor out in the wilderness):
DATABASE []
If I then hit CTRL-L, the screen refreshes, and I see the text as it should be displayed... until I start typing, and then the buffer start acting strangly again (characters disappearing, moving, cursor ending up in the wrong place, etc)
I've not, to my knowledge, added anything to my .emacs file since this last worked as I expect it to, so I'm at a loss as to what could be happening here. It doesn't seem specific to sh-mode either - I've tested a few other file types and observed similar strange behavior. Are there any emacs afficianados out there who might be able to point me in the right direction to figure out what's wrong here?
Thanks in advance
I'm not sure what to suggest, but this sounds awfully like an issue with the terminal: I suspect that Emacs redraws the current line whenever it changes and I guess it tries to do so incrementally. If something's got out of whack with your terminal, then it seems quite plausible that the current word would get written at the start of the line (all Emacs sent) and your cursor would get abandoned "out in the wilderness" :-)
Obviously, this is a new change. Since it doesn't sound like the sort of issue that would be caused by Elisp configurations in your .emacs, you should check whether you've recently upgraded one of
PuTTY
Emacs version
SSH version (unlikely...)
Then maybe the relevant tool will have something in the changelog (which maybe you can disable via a config?)
One thing you could check: you say this isn't just SH-mode. Is it "any mode with syntax highlighting"? Maybe Emacs just sends over the wire the text with the current colour?
I had a similar problem of disappearing text using PuTTY / Emacs / Remote AWS Ubuntu when running ABCL LISP in a shell window.
The solution was: I had changed my foreground and background font colors (essentially reversed) in PuTTY but had neglected to change the bold fonts, so they were disappearing into the background.
