 The regular ''apt-get'' repo is too out-of-date. When 0.9.5 was stable, Ubuntu 20.04 was providing 0.3 or 0.4.
-I could use snap on my work (Ubuntu) and personal frame.work laptop computers to get 0.9.5. (However, [[https://github.com/cli/cli/blob/trunk/docs/install_linux.md#snap-do-not-use|GitHub recommends against snap for gh]], so maybe snap is problematic.)

+===== Copilot Chat =====
+See [[https://github.com/CopilotC-Nvim/CopilotChat.nvim?tab=readme-ov-file#manual|Manual installation of CopilotChat]].
+<code bash>
+mkdir -p ~/.config/nvim/pack/copilotchat/start
+cd ~/.config/nvim/pack/copilotchat/start
+# (Done as part of CoPilot installation) git clone --filter=blob:none --single-branch https://github.com/github/copilot.vim
+git clone --filter=blob:none --single-branch https://github.com/nvim-lua/plenary.nvim
+git clone --filter=blob:none --single-branch https://github.com/CopilotC-Nvim/CopilotChat.nvim
+</code>
+===== Updating Copilot and Copilot Chat =====
+This is a manual process because I only want to do it when I'm ready to handle backwards incompatibilities.
+Update Copilot autosuggest:
+<code bash>
+mkdir ~/backup
+mv ~/.config/nvim/pack/github ~/backup/
+git clone --filter=blob:none --single-branch https://github.com/github/copilot.vim.git ~/.config/nvim/pack/github/start/copilot.vim
+# Test auto suggest. If it works, delete the backup and the /.git dir...
+rm -rf ~/backup/github
+rm -rf ~/.config/nvim/pack/github/start/copilot.vim/.git
+</code>
+Update Copilot Chat:
+<code bash>
+mv ~/.config/nvim/pack/copilotchat ~/backup/
+mkdir -p ~/.config/nvim/pack/copilotchat/start
+cd ~/.config/nvim/pack/copilotchat/start
+git clone --filter=blob:none --single-branch https://github.com/nvim-lua/plenary.nvim
+git clone --filter=blob:none --single-branch https://github.com/CopilotC-Nvim/CopilotChat.nvim
+# If WSL, see if you have to fix XDG_RUNTIME_DIR.
+# Test :CopilotChat. If it works, delete the backups and the /.git dir...
+rm -rf ~/backup/copilotchat
+rm -rf ~/.config/nvim/pack/copilotchat/start/CopilotChat.nvim/.git
+rm -rf ~/.config/nvim/pack/copilotchat/start/plenary.nvim/.git
+rmdir ~/backup
+</code>
+==== macOS tweak ====
+On macOS, I initially had trouble with diffs of the form ''[file:main.cpp](#file:main.cpp-context)'', so I edited [[https://github.com/CopilotC-Nvim/CopilotChat.nvim/blob/main/lua/CopilotChat/client.lua#L25|~/.config/nvim/pack/copilotchat/start/CopilotChat.nvim/lua/CopilotChat/client.lua:25]].
+<code bash>
+sed -i 's/(#file:%s-context)/(%s)/' ~/.config/nvim/pack/copilotchat/start/CopilotChat.nvim/lua/CopilotChat/client.lua
+</code>
+==== WSL tweak ====
+WSL sets ''$XDG_RUNTIME_DIR'' to a path that cannot be written to. So either:
+  - ''export XDG_RUNTIME_DIR=/tmp''
+  - or modify plenary's curl.lua to not find it. (Mangle it.) (See ''sed'' below.)
+  - or ''[[https://github.com/microsoft/WSL/issues/10846#issuecomment-1840548054|sudo chown 1000:1000 /mnt/wslg/run/user/1000]]'' (untested)
+<code bash>
+sed -i 's/XDG_RUNTIME_DIR/DXB_HIDDEN_XDG_RUNTIME_DIR/' ~/.config/nvim/pack/copilotchat/start/plenary.nvim/lua/plenary/curl.lua
+</code>
+==== Optional Settings ====
+Optional, [[https://github.com/CopilotC-Nvim/CopilotChat.nvim/wiki/Examples-and-Tips#markdown-rendering|MarkDown rendering]]:
+<code bash>
+git clone --filter=blob:none --single-branch https://github.com/nvim-treesitter/nvim-treesitter \
+          ~/.config/nvim/pack/nvim-treesitter/start/
+</code>
+Add ''require'nvim-treesitter.configs'.setup...'' to .config/nvim/init.vim. Test CopilotChat like this, with treesitter, but not render-markdown.
+See what you think of this first. (Rainbow parentheses may be gone. Might have to add something like [[https://github.com/HiPhish/rainbow-delimiters.nvim|rainbow-delimiters.nvim]]).
+<code bash>
+git clone --filter=blob:none --single-branch https://github.com/MeanderingProgrammer/render-markdown.nvim \
+          ~/.config/nvim/pack/render-markdown.nvim/start/
+</code>
 ===== taglist =====
-The old taglist I have isn't working as expected in tmux. Try getting the latest release (since head auto runs tests).
+The old taglist I have isn't working as expected in tmux. Opening the window would wrap neovim windows. The fix is to disable auto-resizing the winwidth.
+  let Tlist_Inc_Winwidth = 0
+Along the way, I tried getting the latest release (since head auto runs tests). Maybe I should keep it.
   git clone --filter=blob:none -b v4.6 https://github.com/yegappan/taglist ~/.local/share/nvim/site/plugin/
+===== cscope =====
+Cscope has been removed from neovim. If you want it back, install [[https://github.com/dhananjaylatkar/cscope_maps.nvim|dhananjaylatkar/cscope_maps.nvim]] into ''.config/nvim/pack/cscope_maps/start/''. (This //may// also work in ''~/.local/share/nvim/site/pack/cscope_maps/start/'', but you have to get the path right.)
+Your hierarchy would look something like:
+<code>
+~/.config/nvim/pack/cscope_maps/
+└── start
+    └── cscope_maps.nvim
+        └── lua
+            ├── cscope
+            │   └── pickers
+            └── utils
+</code>
+Run the following commands:
+  mkdir -p ~/.config/nvim/pack/cscope_maps/start/
+  cd ~/.config/nvim/pack/cscope_maps/start/
+  git clone --filter=blob:none https://github.com/dhananjaylatkar/cscope_maps.nvim.git
+Then in your init.vim, add the following snippet:
+<file lua init.vim>
+lua << EOF
+  require('cscope_maps').setup({
+    disable_maps = true, -- Mapping C-] to :Cstag <cword> worse than :tag <cword>
+-- Alternatively, if we liked the mappings, then customise these two:
+--    skip_input_prompt = true,
+--    cscope = { skip_picker_for_single_result = true },
+  })
+EOF
+</file>
+===== Mappings =====
+The easiest way to find out where a mapping came from is to run this command:
+    :verbose imap <key sequence>
