+
+## Text Manipulation
+
+- Add at the end of multiple lines: `:normal A<text>`
+
+  - Execublock: `:A<text>`
+
+  - visual block mode(ctrl + v)
+  - Append text at the end of each line in the selected block
+  - If position exceeds line end, neovim adds spaces automatically
+
+- Delete the last char of multivle lines: `:normal $x`
+
+  - Execute `$x` on each line
+  - visual mode(v)
+  - `$` moves cursor to the end of line
+  - `x` deletes the character under the cursor
+
+- Delete the last word of multiple lines: `:normal $bD`
+  - Execute `$bD` on each line
+  - visual mode(v)
+  - `$` moves cursor to the end of line
+  - `b` moves cursor to the beginning of the last word
+  - `D` deletes from cursor to the end of line

+# a thread is spawned that serves DNS requests and hands down an ip
+# assigned from an internal list (via remote_dns_subnet).
+# this is the easiest (setup-wise) and fastest method, however on

+# this might not work and/or cause crashes.

+# in proxychains 3.1 style. requires `proxyresolv` in $PATH
+# plus a dynamically linked `dig` binary.
+# this is a lot slower than `proxy_dns`, doesn't support .onion URLs,
+# but might be more compatible with complex software like webbrowsers.
+#proxy_dns_old
+
+# method 3. use proxychains4-daemon process to serve remote DNS requests.
+# this is similar to the threaded `proxy_dns` method, however it requires
+# that proxychains4-daemon is already running on the specified address.
+# on the plus side it doesn't do malloc/threads so it should be quite
+# compatible with complex, async-unsafe software.
+# note that if you don't start proxychains4-daemon before using this,
+# the process will simply hang.
+#proxy_dns_daemon 127.0.0.1:1053
+
+# set the class A subnet number to use for the internal remote DNS mapping
+# we use the reserved 224.x.x.x range by default,
+# if the proxified app does a DNS request, we will return an IP from that range.
+# on further accesses to this ip we will send the saved DNS name to the proxy.
+# in case some control-freak app checks the returned ip, and denies to 
+# connect, you can use another subnet, e.g. 10.x.x.x or 127.x.x.x.
